I’m pretty sure it’s just incandescence, but the behavior of it feels odd— it only glows above 9 volts at which point current will pass and it immediately reaches full brightness— no fade-in. If I didn’t know better I’d say it acts like an LED. My guess is that it’s just reaching some breakdown voltage and after which it passes current and glows. Current passed from base-collector. Draws about 300mA at 20 volts. And yes it was already blown— no live transistors were harmed lmao submitted by /u/possibly_random [link] [comments]

Non-volatile memory is an important component in a wide range of high-performance embedded applications. Especially, many consumer, industrial, and medical applications need increased re-writability to support both more frequent code updates as well as increased data logging.

These applications require greater memory density to store either a substantially larger code footprint and/or more extensive data logs. Moreover, developers need to be able to improve power efficiency while lowering system cost.

Today, there are numerous non-volatile memory technologies available to developers, including EEPROM, NOR flash, NAND flash, MRAM, and FRAM. Each has its own distinct advantages for specific applications. However, the combination of 1) manufacturing process technologies continuing to scale smaller, 2) the need for higher densities at lower power, and 3) re-writability becoming increasing important has led to increased interest in RRAM for these applications.

This article will explore RRAM technology and how it provides developers with a new approach to meeting the changing memory requirements of high-performance embedded systems.

Memory in high-performance embedded systems

Emerging connected systems face a number of tough design challenges. For instance, medical devices—such as hearing aids, continuous glucose monitors (CGMs), and patches—must fit into a smaller form factor despite increasing data and event logging requirements necessary to enable remote monitoring and compliance with industry standards.

Next, smart equipment in Industry 4.0 systems require significantly greater code storage to facilitate functionality like remote sensing, edge processing, and firmware over-the-air (FOTA) updates for remote maintenance. Furthermore, the addition of artificial intelligence (AI) at the edge in wearables and Internet of Things (IoT) devices is driving the need for high-performance, energy-efficient non-volatile memory in smaller form factors.

The increased code size and data logging requirements of such systems exceeds the embedded non-volatile memory capabilities of microcontrollers. External memory is needed to match increasing density and performance requirements. However, code and data often need varying capabilities depending upon performance, density, endurance, and data-write size.

Thus, multiple non-volatile memories may have to be used, such as NOR flash for data logging and high-density EEPROM for code storage. This can lead to systems that use several types of external memory, increasing system cost, complexity, and energy consumption.

Ideally, systems can use a single memory type that supports both external code and data storage without compromising performance or functionality for either. An emerging non-volatile technology to fill this gap as a standalone external memory is RRAM.

Resistive RAM

Resistive RAM (RRAM) is a non-volatile random-access memory that was made available commercially in the early 2000s. It operates by changing the resistance of a switching material sandwiched between two electrodes, show on left in Figure 1.

Figure 1 Typical RRAM memory cell consists of one transistor and one resistor (left), and the memory state is altered by applying an external bias across the metal electrodes (right). Source: Infineon

The switching material can be metal oxide or a conductive bridging switching media. A typical RRAM memory cell consists of one transistor and one resistor pair (1T1R) where the resistance of the RRAM can be altered with an external bias applied across the metal electrodes, shown on the right side of Figure 1.

Initially, RRAM was developed as a potential replacement for flash memory. At the time, the cost and performance benefits of RRAM weren’t enough to supersede the advantages of other non-volatile memory technologies, especially as an external memory. However, in recent years, several factors have changed to make RRAM a compelling non-volatile alternative.

Specifically, as embedded systems become more integrated and implemented in smaller manufacturing process nodes with substantially larger code and data storage requirements, the following advantages of RRAM for external memory overtake traditional non-volatile options:

1. Scalability

Some non-volatile memory technologies are limited in their ability to scale, translating to limitations in overall memory density due to footprint, power, and cost. A major advantage of RRAM is that it can be manufactured in a compatible CMOS process, enabling it to scale to process nodes below 45 nm and even down as low as 10 nm.

For example, the memory industry has had difficulty cost-effectively scaling NOR flash memory as the technology seems to be physically limited to between 35 and 40 nm. Scalability has a direct impact on performance, density, footprint, and energy efficiency.

2. Direct write

Data storage for a NOR flash memory requires two operations: an erase operation to clear the target address followed by a write operation. The “direct write” functionality of RRAM eliminates the need to first erase memory. Thus, only a write operation is required to store data. Figure 2 shows the operations required for writing to both NOR flash and RRAM.

Figure 2 NOR flash requires an erase operation before every write operation, increasing write time, energy consumption, and wear on memory cells. RRAM’s ability to direct write speeds write operations, conserves energy, and extends cell endurance. Source: Infineon

This leads to much faster large-scale write operations for RRAM, such as during FOTA updates.

3. Byte re-writeable

Some non-volatile memories perform writes based on page size. For example, NOR flash page size is typically either 256 or 512 bytes. This means every write impacts the entire page. To change one byte, the page must be read and stored in a temporary buffer; the change is made to the temporary duplicate.

The flash must then erase the page and write the entire page back in from the buffer. This process is time-consuming and wears the flash (typically 100k+ writes). In addition, data cells that are not changed are worn unnecessarily. Consequently, data logging with NOR flash requires that data is cached and then written in page-sized chunks, adding complexity and potential data loss during a power event.

In contrast, RRAM write size is much smaller (few bytes) with higher endurance than NOR flash. This is more manageable and accommodates data logging requirements well since cells are worn only when written to. Thus, RRAM is robust and efficient for both code storage and data logging in the same memory device.

4. Energy efficiency

Through optimizations such as byte re-writability and eliminating erase operations during data writes, RRAM achieves better energy efficiency, up to 5x lower write energy and up to 8x lower read energy compared to traditional NOR flash.

5. Radiation tolerance and electromagnetic immunity

RRAM technology is inherently tolerant to radiation and electromagnetic interference (EMI). This makes RRAM an excellent choice for those applications where environmental robustness is essential.

Consolidate code storage and data logging

RRAM is a proven technology whose time has come. It’s an established technology that has been in embedded form in chips for over a decade as an internal non-volatile memory. With its ability to scale to smaller process nodes, provide higher endurance and re-writability at low power, and minimize write time and power consumption through direct write functionality, RRAM delivers high performance without compromising robustness or efficiency (Table 1).

Table 1 The above data shows a comparison between RRAM and other non-volatile memory technologies. Source: Infineon

RRAM is an ideal memory for consolidating both code storage and data logging in a single external memory to simplify design and reduce system complexity, making RRAM a compelling alternative to traditional non-volatile memories for many consumer, industrial, and medical applications.

A fragmented ecosystem

Embedded developers have an ongoing struggle to keep the pace by upgrading compilers and debugging tools, while ensuring the processing hardware going into their systems are right-sized for the application. Conventional embedded development tends to force engineers to stick with an established, often vendor-specific, ecosystem where shifting to a different IDE comes with its own costly learning curves. MCU companies and other manufacturers with a foothold in embedded processing are beginning to release solutions that embrace third-party development environments to appeal to the larger market while also maintaining their place with established customers. 

Microchip’s moves to ease hardware-software codesign

Microchip’s recent release of their AI coding assistant and unified compiler is this company’s signal that they are set to follow this theme of lowering development barriers. The AI coding assistant enables their established MPLAB platform to function within the eminently popular Visual Studio (VS) framework while the unified compiler license combines the MPLAB C compilers: XC8, XC16, XC-DSC, and XC32. 

In a conversation with Rodger Richey, the VP of development systems and academic programs, EDN was able to see how a developer would use the AI coding assistant within the VS IDE. 

AI coding assistant in VS

There are essentially three main pieces to this tool: 

• A microchip chatbot for product questions such as coding-specific questions
• An autocomplete function that predicts with inline code suggestions
• Direct access to technical data in vectorized datasheets allowing users to search for information such as block diagrams without leaving the coding environment

“We have actually been using this internally within Microchip for the last nine months and, depending upon the user, we’ve seen anywhere between a 20 to 40% productivity enhancement,” said Richey, offering a live demo of the VS tool. 

Creating project and searching datasheet

As shown in Figure 1, he began by asking the assistant about the features of the new PIC32CM JH family of MCUs where the assistant replied with details such as core, memory, and peripheral features as well as part numbers. At this point, the tool downloads the vectorized datasheet so that it is searchable within the AI coding assistant, “I’m going to put the part number in and select the compiler,  now what’s happened in the background is the coding assistant has downloaded the vector datasheet.”

Code generation

As shown in Figure 2, Richey begins by asking the assistant to generate code to initialize the UART and ADC, sample once per second, and write to the UART an array of 32. At this point, the tool returns the code and interrupt routines that Richey arbitrarily places within the source code file.

Checking code for errors

The source code is then copied and pasted into the chatbot to check for errors and a number of issues are found (Figure 3). “I inserted the code in the middle of an existing function and what it does is creates a corrected version of the code,” Richey then places the corrected code into the existing file.

Figure 3 Error is copied and pasted into the chatbot and a request to check for errors is placed whereby the coding assistant returns a number of errors found within the code. 

Autocomplete 

At this point, the autocomplete function is highlighted. First, code is created that adds two numbers together (Figure 4). As Richey accepts autocomplete inline suggestions, the tool begins predicting the next steps in the code: creating a function to average the numbers within the array. Figure 4 shows some of these inline code suggestions. Comments can also be added with relative ease by simply asking the assistant to comment the code where the user’s job is limited to rejecting/accepting the comment suggestions. “We want to keep the developers in the flow of writing code. Anything you do is a distraction, even if you have to leave the development environment or even write comments.”

Figure 4 Autocomplete functions create inline comment/code suggestions that the user can accept or reject.

Exploring the datasheet within the IDE

Richey brings up a block diagram of the analog comparator within the development environment by prompting the tool with “show me the block diagram of the analog comparator,” as shown in Figure 5. “If I want to look at what the registers are for, it’ll show me all of the registers and the bits within them.”

Figure 5 Block diagrams for the analog comparators can be viewed within the IDE with a hyperlink that takes the user to the datasheet. 

 At this point, Richey has the tool write code to initialize the comparator which he can then, once more, place arbitrarily within the source code, and check for errors. “Now I’ve got a project open that’s got a lot of directories, and each one of these directories has a lot of files,” Richey goes on to show the “@Codebase” prompt checking for a function to initialize the SERCOM0 module, a UART-to-serial port that is on the PIC32CM JH (Figure 6). At this point, the tool pulls out the relevant piece of code so that the user can drop it into any other file. “I can do an @file where I can go search for a particular file, @folder to bring up all the folders within the project.”

Unified compiler

The MPLAB XC unified compiler licenses just released today are another initiative by the company to simplify the process of working with Microchip’s hardware and software. “Typically, you’ll have a free compiler and an optimizing compiler that you have to pay for. The difference with the optimizing compilers is that they have implemented core- or product-specific optimizations where you’ll typically see ~35% smaller code for a vendor supply compiler relative to, say a GCC [GNU Compiler Collection],” says Richey. The marginal gains can be the factor that pushes engineers into a higher memory, more expensive, device where the cost of a compiler would likely pale in comparison to the per unit savings on a mass-manufactured product. 

“A vendor today will typically supply core specific compilers, so there might be an ARM core, a MIPS core, or a supplier-specific core. As a client this can be difficult to manage. You have to ask yourself how many compilers you need.” And, as the needs for the project change, so do the mix of compilers used potentially creating more overhead for the client since payments for compilers are generally issued on an annual basis. For more stringent industries like industrial and automotive, the clients might stay on a fixed version of a tool for decades, where they must pay for that same version every year.  

“Microchip supports a lot of automotive, medical, industrial, and aerospace and defense clients, and they’re typically fixed on one version, because to upgrade the compiler version forces them to go back through an approval loop and it’s very costly for them, creating a purchasing nightmare.” Microchip is attempting to sidestep these issues with the unified compiler where a single, perpetual license grants access to the MPLAB XC8, XC16, XC-DSC and XC32 C compilers. There is however a voluntary 12-month maintenance fee that is 20% the cost of the compiler. 

Richey finished by highlighting Microchip’s initiatives for easing the development process for embedded engineers using Microchip hardware/software, “Whether it’s IR, Keil, SEGGER, VS, or the Eclipse IDE, we realize that not everyone that’s developing for Microchip is using Microchip tools. So we want to meet the developer and the ecosystem of their choice. We don’t want to force them into our ecosystem.”

As I discussed in early December, my first purchase attempt of a lithium battery-based portable power generator, Energizer’s PowerSource Pro, didn’t pan out. But I didn’t give up. In fact, as I’d alluded to in a writeup published two weeks earlier, I bought two successors, both from the same company, EchoFlow. The smaller RIVER 2 (and no, I don’t know why its marketing-anointed name is all-caps):

is what I’ll be discussing here, with coverage of its more sizeable, flexible DELTA 2 sibling saved for another day (that said, currently scheduled to arrive in your web browser shortly):

With the stock photo out of the way, here’s a shot of my particular unit fresh out of the box and on the workbench, first in overview with its SLA battery-based Phase2 Energy PowerSource 660Wh 1800-Watt Power Station precursor in the background:

And then in closeup, specifically of its front panel display during initial AC-fed charging:

I picked up the RIVER 2 from EcoFlow’s eBay store, supposedly refurbished, for $109.68 after a 20%-off promo coupon, inclusive of sales tax and with free shipping, at the beginning of September. I say “supposedly refurbished” because, in stark contrast to the Energizer PowerSource Pro Battery Generator I’d bought earlier, which was supposedly brand new but arrived in clearly pre-used condition, this one seemingly came fresh and pristine straight from the factory manufacturing line. Why? I suspect it had something to do with the fact that shortly after I bought mine, EcoFlow introduced its gen-3 devices. The RIVER 3’s incremental benefits were modest, as it turned out and at least in my typical use case, such as:

• GaN-based circuitry, resulting in even smaller dimensions than before, along with higher-efficiency (therefore cooler and quieter) operation
• Higher USB-C PD peak output power (100 W vs 60 W), and
• Faster output switching speed from direct to inverter-generated AC, thereby enabling the RIVER 3 to more robustly act as an UPS (<20 ms vs 30 ms)

Although curiously, the RIVER 3’s peak stored charge capacity decreased to 245 Wh versus the RIVER 2’s 256 Wh. My guess is that my good fiscal fortunes were due to a preparatory stealth warehouse-purging move on EcoFlow’s part.

What was my rationale for getting the RIVER 2 in addition to the more sizeable Energizer PowerSource Pro-like DELTA 2? The price tag was certainly an effective temptation. More generally, here’s what I wrote back in December:

[It] is passable for overnight camping trips in the van, for example. Or a day’s worth of drone flying. Or for powering my CPAP machine and oxygen concentrator overnight. And I can use the aforementioned 100-W portable solar panel to also recharge it during the day (albeit not at the same time as the Phase2), in conjunction with an Anderson-to-XT60i connector adapter cable.

That “aforementioned 100-W portable solar panel” is this:

which I’d covered back in September. And in the spirit of “the proof of the pudding is in the eating” (which for today I’m rephrasing as “the proof of the concept is in the pictures”), here are some shots of it hooked up to on my back deck. First, the solar panel itself:

An illuminated light means “working”:

As does this output-voltage reading:

This particular solar panel was originally intended for use with (and still works fine with) the Phase2 Energy PowerSource, whose backside includes an Anderson Powerpole PP15-45 solar charging connector:

To adapt the panel to that generator, as mentioned in more recent coverage, “required both the female-to-female DC5521 that came with the Foursun F-SP100 solar panel and a separate male DC5521-to-Anderson adapter that I bought off Amazon:”

And what about the RIVER 2? Its solar (as well as car, via an included “cigarette lighter”-source adapter cable) charging connector of choice, as mentioned in that same more recent coverage, is an orange-color XT60i:

the higher current-capable, backwards-compatible successor to the original yellow-tint XT60 used in prior-generation EcoFlow models:

So, what did I do to bridge the connection-discrepancy gap? I added yet another cable to the chain, of course:

a third-party Anderson to XT60i adapter I’d found on Amazon:

The resultant setup does indeed passably bump up the RIVER 2 battery charge, assuming there’s adequate available sunshine, although fastest charging results are unsurprisingly achieved with the RIVER 2 tethered to AC as shown earlier. To wit, by the way, my stopwatch happily confirms EcoFlow’s website claim that you can “charge 0-100% in only 60 mins”.

To the “svelte” adjective in this writeup’s title, I’ll offer the following representative specs:

• Dimensions: 9.6 x 8.5 x 5.7 inches
• Weight: approximately 7.7 lbs.

The RIVER 2 standard maximum AC-inverter power output (pure sine wave, not simulated) is 300W, and it also offers a feature branded as X-Boost Mode, which doubles the output AC power (at a reduced voltage tradeoff that not all powered devices are guaranteed to accept, albeit obviously counterbalanced by higher current) to 600W. And speaking of powered devices, what are its AC and DC power output options? I thought you’d never ask:

• Two AC (one two-prong, one three-prong with ground): 120V, 50Hz/60Hz, 300W (along with surge 600W at sub-120V, as just described), pure sine wave, not simulated
• Two USB-A DC: 5V, 2.4A, 12W max
• Cigarette lighter” car DC: 12.6V, 8A, 100W max
• And USB-C (which does double-duty as both an output and another battery-charge input option, along with aforementioned AC and XT60i) DC: 5/9/12/15/20V 3A, 60W max

One other generational comment (adding on to my earlier gen-2 vs -3 comparisons), specifically related to the “lithium iron phosphate fuel” bit in this post’s title. First-generation EcoFlow devices were based on NMC (lithium nickel manganese cobalt) battery technology, which as I mentioned back in late November and again a few weeks later is only capable of a few hundred recharge cycles before its maximum storage capacity degrades to unusable levels in realistic usage scenarios. For gen-2 and beyond, EcoFlow switched to LiFePO4 (lithium iron phosphate), also known as LFP (lithium ferrophosphate), battery formulations. The comparative specs bear out the technology-transition improvements; the first-generation RIVER was guaranteed for only 500 recharge cycles, whereas with the RIVER 2 it’s 3,000. The RIVER 2 product page further elaborates and elucidates on the claimed benefits, which also include a 5 year warranty:

Safe, for up to 10 years of use.

 LiFePO4 Battery Chemistry

 With upgraded long-lasting LFP battery chemistry at its core, charge and empty RIVER 2 Series over 3000 times. That’s pretty much 10 years of everyday use and 6x longer than the industry average. With LFP cells, RIVER 2 Series is safe, durable, and highly efficient, even in warm temperatures.

One final note: the RIVER 2 integrates both Bluetooth and (believe it or not) Wi-Fi connectivity:

You can, for example, both monitor the status of the RIVER 2:

and over-the-air update its embedded firmware:

via a mobile-device intermediary using the company’s Android and iOS app versions.

And with that, I’ll wrap up for today. Let me know your thoughts in the comments!
