Building on decades of experience in serving embedded applications where low power, affordability and ease of development are critical, Microchip Technology has added PIC32CM PL10 MCUs to its PIC32C family of Arm Cortex-M0+ core devices. PL10 MCUs feature a rich set of Core Independent Peripherals (CIPs), 5V operation, touch capabilities, integrated toolsets and safety compliance. The device family targets high-volume applications including industrial control, building automation, consumer appliances, power tools and sensor-based systems. As part of the company’s unified MCU strategy, PL10 devices offer pin-to-pin compatibility with AVR MCUs.

The integrated Peripheral Touch Controller (PTC), along with a 12-bit Analogue-to-Digital Converter (ADC) are designed to provide responsive performance in touch applications and strong noise immunity for analogue signal measurement. Additional on-chip CIPs help offload time-critical, repetitive and deterministic tasks from the CPU to improve real-time performance and power efficiency. The PL10 supports the Cortex Microcontroller Software Interface Standard (CMSIS), enabling the development of modular, reusable application code to accelerate the process.

In addition to support from Microchip’s MPLAB development ecosystem, the PL10 family incorporates industry-standard tools and integrated development environments (IDEs), providing developers with more flexibility in how they build, debug, and deploy their software. Compatible third-party tools include Microsoft Visual Studio Code (VS Code), IAR Systems, Arm Keil, SEGGER, Zephyr and MikroElektronika. AI-driven resources such as the MPLAB AI Coding Assistant offer context-aware code generation and real-time product insights to help accelerate and simplify development.

“PL10 MCUs help engineers more easily migrate to higher performance microcontrollers while maintaining the straightforward development experience, power efficiency and cost structure of our established 8-bit solutions,” said Greg Robinson, corporate vice president of Microchip’s MCU business unit. “As we prepare to introduce a range of new microcontrollers over the next 12-18 months, with everything spanning entry-level to AI-capable devices, Microchip is strengthening its commitment to a comprehensive MCU portfolio designed to meet evolving market demands.”

The PL10 family is designed to comply with various industry safety standards, including International Organisation for Standardisation (ISO) 26262 for functional safety in electrical and electronic systems of road vehicles. Additionally, the MCUs are designed to operate from 1.8 to 5.5 volts, supporting performance in high-noise environments such as automotive, IoT, industrial automation and consumer electronics applications. PL10 MCUs enable simultaneous connection to devices operating at different voltage levels without external level shifters using the integrated Multi-Voltage I/O (MVIO).

КПІ — в європейській еліті університетів: ТОП-350 за QS Europe 2026 kpi пн, 02/02/2026 - 11:26

In today’s power-supply designs, even small wiring and connector resistances can distort the voltage that actually reaches the load. As systems push tighter tolerances and higher currents, these drops become harder to ignore.

Remote sense provides a straightforward way to correct them by letting the supply monitor the voltage at the load itself and adjust its output accordingly. Understanding how this mechanism works—and how to apply it properly—is essential for maintaining stable, accurate rails in modern designs.

Local sense vs remote sense: Where you measure matters

Most power supplies regulate their output using local sense—monitoring voltage at the supply’s own output terminals. This works fine in ideal conditions, but in real systems, the path from supply to load includes resistance from wires, connectors, and circuit-board traces. As current increases, even small resistances can cause significant voltage drop, meaning the load receives less than intended.

Remote sense solves this by relocating the feedback point to the load itself. Instead of trusting the voltage at the supply’s output, it uses a separate pair of sense wires to measure the voltage at the load terminals. The supply then adjusts its output to compensate for any drop along the way, ensuring the load sees the correct voltage—even under dynamic or high-current conditions.

This simple shift in measurement point can dramatically improve regulation accuracy, especially in systems with long cables, high currents, or sensitive loads. Many benchtop and lab-grade power supplies now include this feature, often with a front-panel or software-selectable option to toggle between local and remote sense. When testing precision circuits or powering remote loads, enabling remote sense can make all the difference.

As a sidenote on what local sense really does, it seems many benchtop power supplies now include a simple switch—or sometimes local-sense jumpers—to select between local and remote sense. In local-sense mode, the supply regulates using the voltage at its own output terminals.

Switching to remote sense hands regulation to the separate sense leads, allowing the supply to track the voltage at the load instead. This selectable mechanism lets you match the regulation method to the setup—local sense for short leads and quick tests and remote sense when wiring losses matter.

Figure 2 Wiring diagram shows a power supply with local-sense jumpers installed. Source: Author

Put simply, for a local-sense configuration, you install the local-sense jumpers so that the Sense + and Sense – terminals are tied directly to the corresponding + and – output terminals on the power supply’s output connector. For a remote-sense configuration, all local sense jumpers are removed, and the Sense + and Sense – terminals are routed externally to the matching + and – points at the load or device under test (DUT).

Note at this point that power supplies with a local/remote sense selector switch don’t require separate local sense jumpers. That is, power supplies equipped with a physical or electronic local/remote sense switch (or a digital configuration setting) utilize internal circuitry to bridge the sense lines to the output terminals. This eliminates the need for the external metal jumpers or wire loops typically found on the barrier strips of older or simpler power supplies.

4-wire sensing: More sensible pointers on remote sense

Starting this session with a cautionary note, always verify the selector switch position and all sensing connections before enabling the output. Setting the switch to Remote without sense wires attached can trigger the feedback loop to detect zero voltage and attempt to compensate. This often forces the power supply to its maximum voltage, potentially damaging your equipment even if physical jumpers are absent.

Furthermore, any noise captured by the sense leads will be reflected at the output terminals, potentially degrading load regulation. To minimize electromagnetic interference (EMI) from external sources, use twisted-pair wiring or ribbon cables for the sense connections.

Because these high-impedance leads carry negligible current, thin-gauge wire is sufficient for this purpose. In high-noise environments, shielded cabling may be necessary; if used, ensure the shield is grounded at the power supply end only and never utilized as a current-carrying sensing conductor.

As a quick aside, it appears that many power supplies now implement some form of smart sense detection as a fail-safe. Since a floating sense connection can create a hazardous open-loop state, these systems protect the hardware by shutting down if the leads are disconnected—whether that happens during live use or at initial startup.

In practice, many modern programmable power supplies use auto-sense technology to monitor sense terminals and automatically engage remote sensing when external leads are detected. To ensure stability, these units include internal protection resistors—often called fallback resistors—connecting the output and sense terminals.

These resistors provide a secondary feedback path that allows the supply to default safely to local sensing if leads are missing or accidentally disconnected. This hardware redundancy prevents a dangerous open-loop overvoltage condition, protecting the load from upsurges caused by wiring failure or human error.

Just a sidewalk, ordinary yet essential, becomes a metaphor for design simplicity. On a workbench scattered with piles of discrete electronic components, it’s equally instructive and rewarding to attempt the design of an entry-level remote-sense power supply.

Experimenting with various operational amplifier configurations—specifically differential and error amplifier circuits—alongside voltage references demonstrates how feedback loops maintain precise regulation under dynamic loads.

Such a hands-on approach not only highlights the critical aspects of stability and compensation but also provides valuable insight into the trade-offs between component selection, circuit topology, and overall performance. These complexities are left for the reader to explore intentionally.

Virtual remote sense in practice

Jumping to a quick coffee break, let us touch on virtual remote sense (VRS). This clever technique emulates the benefits of true remote sensing without the extra wiring, helping designers maintain regulation accuracy while simplifying layouts.

Several well-known ICs in the Analog Devices’ portfolio—originally developed by Linear Technology—have embraced VRS to make implementation straightforward: LT4180, LT8697, and LT6110 are prime examples. Each integrates features that reduce voltage drops across traces and connectors, ensuring stable supply rails even in demanding applications.

Because these devices employ different methods to achieve VRS, a thorough review of their datasheets is strongly recommended to understand the nuances and select the right fit for your design. Exploring these solutions hands-on could be the key to unlocking cleaner, more reliable power delivery in your next project.

I actually started working on that over 10 years ago, but my electronics knowledge was basically inexistant and it feel apart quickly. Now that 3d printers are a thing and pcb design is more easily accessible, I wanted to achieve that old dream of making a portable N64 myself. I've been working on that project for the past 3 months and it's now complete. Designed the whole case myself in fusion 360, printed in PETG for heat resistance. Designed a few PCBs for controller and audio amplifier. Here's a list of features: Complete N64 with expansion pak 7Ah, 7.4v battery pack Speakers / Headphone jack / Volume knob combo PCB designed by myself. 0.5w speakers, surprisingly loud Switch joystick and buttons, N64 original triggers 4:3 5 inches LCD screen USB-C PD, 9v charging port, can charge and play at the same time Custom PCB for low battery indicator, green led when turned on, turns red when battery low Second, yellow LED that turns on when in charge, turns off when fully charged Single L/Z combo trigger with a switch beside the trigger to change which it is Memory pak to come, still waiting for pcb and fram chips Fully works with original cartridges, as well as my summercart64. A bit on the thicker side because of the expansion pak, but I'm happy for a first time. At first I did a ram swap, soldering two 4MB ram chips in place of 2MB chips, thus removing the need for the expansion pak, but down the line I fried the board somehow.

Hey all, I’m a 2nd year student in electronics right now. I know there’s tonnes of handwired keyboards on the internet, but here’s mine. This is my first time ever soldering or doing anything outside of arduino or simulations. So it’s very messy. After I finished painstaking soldering the diodes and columns, it turns out I need 19 pins and the pro micro has only 18. I thought my project was a goner, but I found the hack of removing the resistors in the leds to free 2 more pins. I’d never ever done soldering before, and was honestly scared about taking out the resistor from the board, but figured the project wasn’t going to go anywhere if I didn’t do it, so I took the chance and somehow managed to desolder the resistors and put in the legs of the diode which I cut off earlier! But but but, as soon as I started soldering it to a column to test, I ripped out the copper trace from one of the pins and though my project was a goner (again). Thankfully that hack gave me 20 pins, which means I had exactly 19 now (phew). Maybe you notice the red electrical tape on the switch, that’s because it was meant for the big L shaped enter key which I didn’t have, so I had to use the tape to fit the enter and |\ keys. Well, it works now; it’s not perfect, the board sometimes misses strokes when I use it because the wires the dangling out, and I currently don’t have anything to secure the back. But it works! I’m sorry if my body too long or not technical enough, I just wanted to share my work. When told we’re working on something, profs always ask its application and what issue it resolves. I spent a lot of time and energy on this and I have no answer to these questions, I made it cause I wanted to know how it works and cause I felt I should be able to make it, and I know it’s nothing special or solving any real issue and has a lot of documentation and YouTube videos to make the same. So, I’m just not sure if this work is “sciency” enough to justify it on my profile or even investing that much time into it. Welp, I had fun so that’s that. Sorry for the out of topic rant again. Let me know what you guys think! submitted by /u/Professional_Ice_796 [link] [comments]
