Product line offers a lower-cost alternative to parallel SRAM with up to 4 Mb density and 143 MHz SPI/SQI communications

To address a common customer need for bigger and faster SRAM, Microchip Technology has expanded its Serial SRAM product line to include larger densities of up to 4 Mb and increased Serial Peripheral Interface/Serial Quad I/O Interface (SPI/SQI) speed to 143 MHz. The 2 Mb and 4 Mb devices are designed to provide a lower-cost alternative to traditional parallel SRAM products and include optional battery backup switchover circuitry in the SRAM memory to retain data on power loss.

Unlike parallel RAM, which requires large packages and at least 26–35 microcontroller (MCU) I/Os to interface, the Microchip serial SRAM devices come in a lower-cost, 8-pin package and utilize a high-speed SPI/SQI communication bus that only requires 4−6 MCU I/O pins for easy integration. This reduces the need for a more expensive, high-pin-count MCU and can help minimize the overall board footprint.

Addressing the most common drawback to serial SRAM—that parallel is faster than serial memory—the 2 Mb and 4 Mb serial SRAM devices have increased the bus speed capability to 143 MHz with optional quad SPI (4 bits per clock cycle), which greatly minimizes the speed gap between solutions.

“Serial SRAM is a popular solution for engineers who need more RAM than what is available on board their MCU but are looking to reduce cost and overall board size,” said Jeff Leasure, director of Microchip’s memory products business unit. “Microchip’s 2 Mb and 4 Mb serial SRAM devices are intended to replace expensive parallel SRAM with an easy and cost-effective alternative.”

The small-form-factor, low-power, high-performance serial SRAM devices have unlimited endurance and zero write times, making them excellent options for applications involving continuous data transfer, buffering, data logging, metering and other math- and data-intensive functions. These devices are available from 64 Kbit up to 4 Mb in density and support SPI, SDI and SQI bus modes.

Information is increasingly becoming critical for success in modern SMT production. To get the most out of your manufacturing equipment, you must collect data across the board, process it in a user-oriented manner, and make it available in the right place. Advances in SMT production are characterized by increases in automation, standardization, and integration. While the early days of electronics manufacturing were marked by an approach that featured lots of manual support and was insular and closed-off in terms of information technology, a strong trend towards automation has developed in recent years that is driven by high personnel costs and a shortage of skilled workers due to demographic factors.

The people-free “lights out” factory, however, turned out to not be a sensible optimization goal for economic reasons alone because automation lowers unit costs only to a certain degree. Over-automation, on the other hand, drives up costs. In practice, the Pareto principle, which states that 80 percent of the results are achieved with 20 percent of the resources employed, applies here as well. Each additional percentage point of improvement requires a disproportionate increase in resources. ASMPT recognized this early on and reached the first stage with the Integrated Smart Factory, which focused on maximizing the return on investment instead of automation.

The introduction of standardized interfaces to improve the manufacturing processes in the Integrated Smart Factory was an essential factor for the increasing integration of existing hardware and software solutions. Of particular importance are:
•    IPC-HERMES-9852 for the seamless machine-to-machine (M2M) communication
•    IPC-2591 CFX for linking machines and autonomous storage and transport systems to higher-level systems such as MES and ERP
The global innovation and market leader uses these standard industrial interfaces for its open and flexible automation concept which easily integrates third-party systems, enables retrofits, and gives electronics manufacturers the freedom to choose how, when and to what extent they want to automate their production. With this strategy, electronics manufacturers are precisely geared to the needs of users and the market in terms of their degree of digitalization and automation. The approach was subsequently complemented with software solutions for personnel deployment, quality assurance and material logistics.
The Integrated Smart Factory already features direct machine-to-machine communication – for example, the SPI system can trigger offset corrections or cleaning cycles in the solder paste printer without user intervention. The individual production and quality assurance stages, however, are still largely isolated from each other. In addition, an important resource is hardly used in an integrative way: the data that the numerous cameras, sensors and readers on the individual machines continuously produce.
In contrast to pure machine manufacturers or pure software developers, ASMPT as a system supplier covers almost the entire SMT production with its products, has unique process know-how, and knows from many years of experience which data from the production ‘data lake’ is truly relevant.
By advancing the Integrated Smart Factory into the intelligent factory, ASMPT is now leveraging this treasure trove of data and consistently using big data to optimize the return on investment both in depth, i.e., in the form of more detailed production process analysis and optimization, and across the board through the data-based integration of production areas such as the company’s intralogistics.
It is no longer just the individual process step, the individual machine, the individual setup, the individual product or the individual material requirement that is being considered, but the SMT production in its totality. This new concept of integrative data use in the intelligent factory brings benefits on several levels.

The basis of any improvement in SMT production is the continuous collection and presentation of key performance indicators (KPIs). These include, for example, the line’s throughput rate, overall equipment efficiency (OEE), utilization, and balance. To make this possible, the intelligent factory accumulates machine data in a monitoring application that is part of ASMPT’s Works software suite and makes it available in a way that is role-specific and device-independent.
With their SPI and AOI systems, modern production lines already have highly powerful quality assurance systems. Unfortunately, many of the faults they detect do not originate where they are first discovered. While these systems were able to reject faulty products, they often did not help in eliminating the underlying problems. In the intelligent factory, on the other hand, easy-to-use overarching dashboards quickly reveal what led to these errors. The data integration extends beyond the line. By comparing planning, reference and real-time production data, production obstacles are identified and can be eliminated – again through comprehensive analyses.
The M2M data flow delivers another plus in user-friendliness: Since faults that have been detected by WORKS’ multi-line analysis functions appear on the display of the affected machine, the maintenance staff knows right away where they need to take action.

Since providing the right material in the right quantity at the right time in the right place has always been the goal of intralogistics, the integrative use of data in the intelligent factory has also revolutionized the flow of materials. For example, it is now possible to continuously compute the material consumption on the line in real time in freely definable time slices. The system combines and correlates data on planned and actual material consumption along with data on material currently along the line. Based on this information, WORKS generates material requests to the central and local storage sites along with time-controlled transportation orders. In this way, space-consuming “emergency stock” on the line can be avoided, and the material is available on time and exactly where it is actually needed.
Material buffering in the setup preparation area can also be optimized easily and efficiently with WORKS. Once a production order has been completed, the software provides the employees on the line with detailed instructions as to which component reels need to be returned to the warehouse and which should remain in the setup preparation area because they will be needed again for one or more subsequent orders. This saves time and unnecessary material travel between the shop floor and the central warehouse.
The factory-encompassing management and coordination of autonomous storage and transport systems for all production-relevant materials and tools – from the receiving of materials to the shipping of finished products – is now data-based as well.

A good practical example of the benefits of the integrative use of data is the setup changeover for a new product. In the intelligent factory, the line no longer needs to be emptied – the program changeover can be executed automatically by passing the data of the circuit board being processed from machine to machine via the standardized IPC-HERMES-9852 interface.
As soon as the PCBs are unloaded from the magazine at the start of the line, all relevant data is sent to the DEK TQ solder paste printer from ASMPT. This can be done via labels and a barcode reader or directly from the production planning system. The machine then compares the data with the information stored in the planning system. If necessary, it triggers an automatic program download and any setup changes that may be required. Once printed, the circuit board is passed along to the Process Lens SPI system along with its IPC-HERMES-9852 data and subsequently to the SIPLACE placement machines. Each manufacturing station executes a new comparison between the loaded and the required program and makes any necessary updates. Thanks to these PCB-induced program changeovers, multiple products can be manufactured simultaneously on a single line. Even the conveyors adapt automatically to the width of the circuit boards being transported. And in case of a family setup, these product changeovers can be executed with no operator assist whatsoever.

The intelligent factory does more than control the machines based on data – it also supports the most important production resource of all: people. Scarce specialists are no longer tied to a specific line but can be deployed across the entire shop floor based on their soles and qualifications. To do this, the state-of-the-art staff management application in WORKS interfaces with the material flow planning system. If, for example, manual support is required for a setup change, a corresponding request appears on an operator’s device automatically and with sufficient lead time. And if the task can be carried out remotely, this is done conveniently via a remote cockpit. In this way, SMT lines can be kept running continuously, making the whole factory more productive. With software for all of the factory’s maintenance and repair tasks, teams of technicians can easily balance on-demand maintenance and ongoing production tasks, effectively managing all assets from whole machines to individual nozzles. When unforeseen problems arise, an AI- and NLP-based virtual assistant with an extensive knowledge base supports root cause research and troubleshooting – and best of all, you can simply ask it questions using your voice, just like talking with an experienced colleague.
“Thanks to standardized interfaces, what belongs together is now growing together in the intelligent factory,” says Bernhard Fritz, Head of Global Marketing at ASMPT SMT Solutions. “Material flow and quality management, planning and the factory floor, man and machine – all production factors are merging into an integrative whole. And the overarching improvement goal is always the best possible utilization of existing capacities – and above all, the maximum return on investment.”

The global renewable energy market has been experiencing substantial growth, driven by the increasing demand for clean and sustainable energy sources. Solar energy, in particular, has gained prominence as a key player in the renewable energy landscape. According to a report by Mordor Intelligence, the renewable energy market has now reached pre-pandemic levels, signifying its resilience and continued growth. This growth is attributed to various factors, including government incentives, technological advancements, and an increased awareness of environmental concerns.

The industry is constantly evolving to further enhance the efficiency and financial viability of photovoltaic (PV) systems. One critical aspect of this evolution is the need for 1500VDC PV systems. However, this transition presents challenges for DC-DC converters in supporting higher voltages. This week, we explore the progression and recent challenges of PV systems and consider how the solar market stands to benefit significantly from the AE15B-EW and AE15B-UW DC-DC converters from CUI Inc.

To remain competitive and sustainable, photovoltaic systems must continuously improve their efficiency and financial viability. This drive for improvement stems from several considerations.

First, maximizing energy output. Efficiency is fundamental in solar energy generation. By increasing the efficiency of PV systems, more energy can be harnessed from the same amount of sunlight. This leads to higher energy production and better returns on investment. Facilities like the National Renewable Energy Laboratory (NREL), part of the US Department of Energy, regularly conduct testing of PV cells (Figure 1) and modules to ensure consistency and accuracy of PV performance metrics.

Second, reducing the installation costs. Financial viability is a crucial aspect of any solar project. Lowering installation costs, such as hardware and labor, can make solar energy more affordable for consumers and businesses alike. This is essential for the widespread adoption of solar technology.

Lastly, adapting to new technologies. The solar industry must continually adapt to emerging technologies, such as advanced materials and improved manufacturing processes. These innovations contribute to both increased efficiency and reduced costs.

One significant development in the solar industry is the transition from traditional 1000VDC PV systems to 1500VDC PV systems. This increase in voltage has several advantages. Primarily, it improves the overall energy transmission. Stepping up to higher voltage systems allows for efficient electricity transmission over longer distances. This is particularly beneficial for large-scale solar installations and solar farms. Increasing the voltage also helps to mitigate electrical losses during energy transmission, resulting in less energy waste, thereby contributing to higher overall system efficiency. Also, 1500VDC systems require fewer electrical components, such as cables and connectors, leading to cost savings during installation and maintenance.

While the transition to 1500VDC PV systems offers numerous benefits, it also presents challenges for DC-DC converters, which play a critical role in these systems. For instance, DC-DC converters must be capable of handling the increased voltage levels in 1500VDC systems. This requires robust and reliable components to ensure safety and system stability.

Also, system efficiency is critical. Maintaining high efficiency levels in DC-DC converters is essential to maximize the energy harvested from solar panels. Any loss in efficiency can impact the overall performance of the PV system. Lastly, solar installations often operate in harsh environments with temperature variations and exposure to the elements, meaning DC-DC converters must be rugged and reliable to withstand these conditions over an extended period.

In the face of these challenges posed by the transition to 1500VDC PV systems, CUI Inc. offers solutions that help shape the future of renewable energy.

CUI Inc.’s AE15B-EW and AE15B-UW DC-DC converters (Figure 2) are 15W isolated modules designed for 1500VDC PV systems. These DC-DC converters are engineered to address the high voltage challenges while ensuring safety and reliability while delivering cost savings. Likewise, efficiency is a key focus, with the AE series boasting high efficiency levels to minimize energy losses and maximize solar energy output. These converters are rugged and reliable, built to endure remote outdoor solar installations and harsh environmental conditions, ensuring the longevity of PV 11 systems.

Available in board, chassis, and DIN rail mounting options, the AE series features power ratings from 5W to 40W. They excel in renewable energy applications, including solar power equipment, wind turbines, and electric charging stations. With an ultra-wide input voltage range of 200 to 1500VDC, input ratio ranges of up to 10:1, and robust 5600VDC input-to-output isolation, these modules are suitable for various setups.

The AE series is rated for operation at altitudes of up to 5000 meters and can withstand temperatures from -40°C to +70°C at full load, making them ideal for remote, high-altitude environments. Continuous over-current, over-voltage, and short-circuit protection with automatic recovery further enhance system reliability.

As the renewable and solar energy markets continue to grow globally, the need for innovative solutions becomes increasingly apparent. Photovoltaic systems must evolve to maximize energy output, reduce costs, and adapt to new technologies. Hence, the transition to 1500VDC PV systems offers numerous benefits, including improved energy transmission, reduced electrical losses, and lower installation costs. However, this shift presents challenges for DC-DC converters in handling higher voltages while maintaining efficiency and reliability.

CUI Inc.’s AE series of DC-DC converters excel in addressing these challenges, offering high voltage handling, enhanced efficiency, and robust durability, making them an ideal choice for solar applications. These converters play a pivotal role in unlocking the full potential of renewable energy.

Rohde & Schwarz will present the first real-time measurements on the planned new Bluetooth signals to support Channel Sounding. The demonstration at the embedded world Exhibition & Conference in Nuremberg, Germany, will be run on an R&S CMW500 wideband radio communication tester. The Bluetooth Channel Sounding feature will enable unprecedented positioning accuracy for consumer and commercial applications. The signal measurement capabilities to support chip and device development are eagerly awaited by the industry.

For consumer and commercial devices, Bluetooth is the most widely installed technology with location-determining capabilities. Channel Sounding, soon to be introduced, will significantly improve the accuracy of real-time location services for determining position using Bluetooth to an accuracy of 50 cm or better. In addition to improved location accuracy, Channel Sounding is expected to consume less power than existing Bluetooth location services and provide increased security. The improved accuracy will be a major step forward in particular for indoor applications such as asset tracking on the factory floor or in the warehouse, as well as for secure access to buildings or vehicles.

Hardware changes for Bluetooth devices introduced on a new physical layer are required to support the improved location functions. Engineers who want to start developing the necessary chips and devices, including support for Channel Sounding urgently require reliable and accurate measurements on the signals that enable the new functions. Rohde & Schwarz has already prepared options for its R&S CMW platform to support the corresponding RF physical layer measurements.

The STSPIN32G4 integrates a three-phase gate driver, an STM32G431, and a power management system under one package to solve major engineering challenges, thus enabling new applications. While ST continues to offer STSPIN motor drivers, we also realized that engineers still face several conundrums. Designers want to run more powerful applications but must also shrink their PCBs and reduce costs. Similarly, applications demand more efficiency, but improving it by a few decimal percentage points remains a struggle. ST engineers thus launched the STSPIN32G4 because no other integrated motor controller offered such a powerful mainstream MCU and such a flexible power management system.

Let’s take the example of an engineer working on a high-end vacuum cleaner with a high-speed motor. The MCU inside the STSPIN32G4 will stand out, in this instance, because of its computational throughput. A lower-performance CPU core means a lower conversion rate when designing a field-oriented control (FOC) sensorless application. The engineer in the vacuum cleaner example would have to use two or three shunt resistors to compensate for the MCU’s lower performance. On the other hand, the greater computational throughput means a single shunt is sufficient. As a result, using the STSPIN32G4 enables the creation of a powerful application with fewer components.

A team working on a collaborative robot or a guided vehicle would also appreciate the MCU in the STSPIN32G4 for reasons other than the bump in DMIPS. In this instance, engineers must drive two sets of wheels, but traditional motor controllers don’t have enough analog-to-digital converters to handle such a task. As a result, engineers end up using two motor drivers. The STSPIN32G4 is unique because it provides two sets of PWM timers and 12-bit ADCs, among other things. It, therefore, becomes possible to drive two motors with just one integrated device.

While it’s impossible to enumerate all the features in the STSPIN32G4, the reality is that its integrated nature is one of the best ways to solve the space challenge. Motor control applications are increasingly smaller, whether for convenience, costs, or to stand out better. Thanks to its integrated nature, the STSPIN32G4 helps reduce the overall design size by 65% compared to discrete solutions. Practically, it allows engineers to put the control system at the back of the motor and design a much smaller e-bike, vacuum cleaner, or power tool, among other things.

According to our benchmarks, using the new device lowers the overall power consumption by 3% to 5% compared to a system that uses external components. A saving of just a single percent already has a significant impact. ST provided such power efficiency by bringing the typical standby consumption to only 15 µA thanks to a very low-quiescent regulator. Hence, we expect engineers to create significantly more compact designs without needing an external cooling system, thus lowering the BoM.

The motor controller also supports a supply voltage of up to 75 V, compared to only 48 V previously. Additionally, the STSPIN32G4 comes with an over-current protection mechanism and a drain-source voltage (VDS) monitoring system that acts as a redundancy. It monitors the external MOSFETs and turns all gate driver outputs off if it detects an over-voltage condition. As a result, we expect engineers to use the STSPIN32G4 in appliances. Indeed, a white good connected to a grid often suffers from wide voltage variations from the mains. The greater supply voltage range and protection features of the new device will better handle these abnormal conditions.

Engineers sometimes shy away from integrated solutions, fearing they may restrict their optimization capabilities. Hence, ST ensured a high level of customization. For instance, developers can program registers through an I2C interface to use the STSPIN32G4’s VCC buck converter. Moreover, we published an application note showing how to use the buck regulator in a buck-boost configuration by adding a few external components. Finally, engineers can bypass the buck and LDO regulators to rely on only an external Vcc supply.

Teams that designed a highly precise power supply to meet the stringent requirements of their application can, thus, ignore the STSPIN32G4 regulators. In contrast, others can simplify their designs by using its VCC buck converter to power a few external components, like a memory module. Similarly, developers can choose to enable or disable the standby mode. Such a feature is vital for products like power tools. When users pick a drill after months or even years, they must use it immediately. In such a case, engineers will want to completely disconnect their system from the battery to maximize its usage.

Engineers also get a lot more flexibility in how they drive a motor. They could use a 6-step driver circuit or a field-oriented control, both with or without a sensor and with one, two, or even three shunts. It gives developers the ability to control how much measurement data they gather. Consequently, it also becomes possible to qualify an STSPIN32G4 and use it in many different applications, which can help a company shorten its time to market and optimize its operations.

ST launched two development boards to enable teams to test and experiment with the STSPIN32G4. The EVSPIN32G4 uses STL110N10F7 power MOSFETs and a heat sink to allow an output current of up to 20 A RMS. As a result, teams can push the new devices to develop more powerful designs. However, ST is also mindful that not every designer will use the STSPIN32G4 in high-powered systems. Hence, we are also launching the EVSPIN32G4NH, a similar development board without passive cooling; NH at the end of the nomenclature stands for “no heat sink”. We also updated the X-CUBE-MCSDK to support the new boards and devices.

More recently, our teams released two reference designs. The EVLSPIN32G4-ACT drives a three-phase brushless motor supporting up to 5 ARMS and can manage a supply input of 48 V for a surprising 250 W total power in a board measuring only 62 mm x 50 mm. Additionally, it can connect to the STWIN.box (STEVAL-STWINBX1) to rapidly create a high-speed data logger. Thanks to our FP-IND-DATALOGMC software pack and Quick Start Guide, engineers have a step-by-step process to connect both boards and run applications that can gather data from the sensors on the STWIN.box and the motor itself. We even offer a GUI to help visualize the information.

The other board is the EVSPIN32G4-DUAL, which combines the STSPIN32G4 and the STDRIVE101, a triple half-bridge gate driver. As a result, the board can drive two three-phase brushless motors for up to 10 ARMS output current and a supply of 74 V thanks to two power stages. Thanks to the operational amplifiers of the STSPIN32G4, it’s possible to have a sensor-less system with a single shunt current sensing or use Hall sensors and encoders with the embedded MCU. Put simply, the reference design shows how to create a powerful dual motor application in a small factor for home appliances, e-mobility, pumps, tools, and more.

Anritsu will provide two interconnected compact and lightweight handheld measuring instruments, MT1040A, that will simultaneously transmit and receive high-bandwidth 400-Gbps traffic, thereby demonstrating the end-to-end performance of the multi-vendor network. The MT1040A flexibly supports standard protocols such as 400G Ethernet, OpenZR+, OpenROADM, and more. It provides real-time measurements of the physical layer (Layer 1) Pre/Post FEC BER, as well as Ethernet (Layer 2) latency and throughput.

Through this collaboration, Anritsu will contribute to forums such as the IOWN Global Forum, Open ROADM, and OpenZR+, with the realization of a data center exchange (DCX) based on the IOWN Open APN architecture. In addition, we will contribute to the construction of automated systems used for orchestration that integrate higher-level network management.
