This week's EYE ON NPI is Pretty Sweet Of Course! It's the Infineon Technologies PSOC Control C3 Microcontroller Line (https://www.digikey.com/short/8cw3wpp8) a souped-up microcontroller that is a perfect choice for engineers who need to do some motor control while also managing buttons, LEDs, displays, and other product requirements all on one chip. With a the high-speed ADCs on board, you can manage your BLDC motors and handle the feedback loop in firmware for dynamic tuning without the expense of a specialized co-processor. The PSOC Control C3 series comes in two flavors, the Entry and Main line chips (https://www.infineon.com/cms/en/product/microcontroller/32-bit-psoc-arm-cortex-microcontroller/32-bit-psoc-control-arm-cortex-m33-mcu/psoc-control-c3m/). Both are based on the Arm Cortex M33 which means you know that your CMSIS-based code will be an easy compile and you can use existing pre-compiled libraries. The M33 line is an upgrade to the M3 and M4, giving you the same or better clock speeds and FPU/DSP commands you get with the M4 plus TrustZone and better power efficiency. The Entry line runs at 100MHz, with max 256k Flash 64K SRAM, 10-bit DAC, a 6 MSPS 12-bit ADC, 16 x 16-bit + 4 x 32-bit TCPWMs and a "CORDIC math coprocessor". The Main line can run at 180MHz, same Flash/SRAM and TCPWMs, and has a 12 MSPS ADC plus 4-channel HRPWM with less than 100ps resolution. Both come in 48 and 64 pin TQFP/QFN varieties, the Main line also has an 80-pin version. (There will also apparently be a Performance line, so far un-announced, which may offer more memory / higher frequency). Both have FPU/DSP support, so you'll be able to process the 6 or 12-MSPS ADC data quickly. And the CORDIC processor (https://en.wikipedia.org/wiki/CORDIC) optimizes trig functions like sin/cos/tan/ln so you don't need lookup tables for performing these floating point calculations. These are particularly useful when handling motor motion calculations since they are often sinusoidal and we need to convert to-and-from the ADC measurements to the precision PWM timers. There's a huge selection of Arm processors out there, but the PSOC Control C3 has the best peripherals for motor control: it's rare to see 12MSPS 12-Bit ADC plus so many 16-bit and 32-bit timers with high-speed PWM. The CORDIC co-processor especially will make managing BLDC or Stepper motors a breeze. Plus you still get all the peripherals you would expect of a microcontroller: I2C, UART, SPI, CAN bus, DAC, IRQs, and lots of GPIO. That means you can handle all the other stuff your product has to do while also managing the motor in the background, saving you lots of space and money in BOM costs and fewer integration woes when trying to communicate between a main processor and a motor-control co-processor. The KITPSC3M5EVK eval board (https://www.digikey.com/en/products/detail/infineon-technologies/KITPSC3M5EVK/25880112) is in stock right now if you want a ready-to-go kit at a good price. It comes with 'Arduino shield compatible" pinouts plus a USB / debug interface, and MikroBus connector for expansion. You can also pick up just the bare chip - for example the PSC3M5FDS2ACQ1AQSA1 (https://www.digikey.com/short/8cw3wpp8) is a fancy version with 256K of flash, the 12 Msps ADC, and hall encoder in a TQFP-64 package. It's in stock now at DigiKey for immediate shipment! Order today and you can have a powerful microcontroller with excellent motor feedback control in your hands by tomorrow morning.

For this week's EYE ON NPI, we'll Hazard a guess that you'll be excited to see the Raspberry Pi RP2350 chip available for purchase at Digi-Key for integration into your next design. We've been working with this chip for a few months and it's quickly becoming our favorite Arm Cortex chip, with fun peripherals and a well-supported toolchain. It also is one of the first mass-produced RISC-V chips: one that you can buy and start using for trying out RISC-V development without the 'risc' of worrying you may have picked the wrong core. Available in two chip sizes and with a boost in performance and peripherals, the RP2350 (https://www.digikey.com/short/mzpjhptm) represents a big upgrade to the RP2040 (https://www.digikey.com/en/products/detail/raspberry-pi/SC0914-13/14306010) that you've seen take over the microcontroller world over the last 4 years. Raspberry Pi is famous for their single board computers (https://www.digikey.com/en/products/filter/single-board-computers-sbcs/933) so much so that they created a full market for sub-$100 all-in-one PCs. The big disruption we feel they brought to the market was the creation of a hackable and open-source ecosystem with good main-line OS and driver support. With well-written documentation and up-to-date Linux software, purchasing a Pi meant you got to join in with a community that was having fun, not struggling with compiling out-of-tree kernel modules and closed-source firmware. So in 2021 when they announced the RP2040, folks were interested: could a SBC maker design low power silicon? Turns out, yes! The RP2040 was a fun dual-core 133 MHz Cortex-M0+ processor, with 264K of SRAM, with a satisfying collection of peripherals: USB, ADC, UART/SPI/I2C, PWM, DMA and timers plus the nifty PIO state machine (https://www.raspberrypi.com/news/what-is-pio/). The killer feature, though, was the price: at $1 a chip, and tons of availability with an on-going chip shortage, the RP2040 won our hearts and soldering stations! Three years later, Raspberry Pi is back with a sequel: The RP2350A (https://www.digikey.com/en/products/filter/microcontrollers/685?s=N4IgTCBcDaIE4AcwGYCsAGAgiAugXyA) and RP2350B (https://www.digikey.com/en/products/filter/microcontrollers/685?s=N4IgTCBcDaIE4AcwGYCsAGAQiAugXyA) two variants of an upgrade chip that keeps what was great about the '2040 but with some boosts. First up, the core was upgraded from dual Cortex-M0's to the M33: this means you get an FPU and better low-power performance, plus TrustZone security. The core is spec'd for 150MHz but we've overclocked it to 264MHz without too much complaint. You also have the option to get dual RISC-V cores (https://riscv.org/) instead. SRAM was also bumped: from 264K to 520KB. This is great for running interpreted languages like MicroPython (https://micropython.org/) or CircuitPython (https://circuitpython.org/). Like the original, the RP2350 does not have any built in FLASH memory. Instead, you will need to wire it to a QSPI flash memory chip (https://www.digikey.com/short/80t4zt5t). This way you can pick from 1 MBytes to 16 MBytes whatever your code size needs. This new chip adds the ability to wire in PSRAM (https://www.digikey.com/short/d8033bfw) to the same QSPI bus plus an extra chip select. This is not going to be nearly as fast as on-chip SRAM, but it's great when you want large working memory that the chip will manage for you: by configuring it in the CMakefile, you 'magically' get a huge area you can malloc. Another improvement is in the number of PIO blocks: the original had 2, the RP2350 has 3. The two biggest new features we found are the new HSTX peripheral and the 80-QFN RP2350B (https://www.digikey.com/en/products/filter/microcontrollers/685?s=N4IgTCBcDaIE4AcwGYCsAGAQiAugXyA) variant. HSTX stands for High Speed Transmission and its a high-speed peripheral that can drive 8 output lines - note that it's output only! There's a few possible use cases, but the core reasoning is that this lets you control a DVI display directly from the chip using just the DMA and internal memory without requiring overclocking, PIO, or an extra core. Note that the built in SRAM limits the size of the display if you want to have a video buffer: you can do 320x240 @16bpp or 640x480 @8bpp but, still! Second, if you found the original QFN-60 a bit constraining in terms of GPIO, the QFN-80 'B' version has 20 extra GPIO available for just 10 cents more. If you've been doing grabby-hands in hopes of getting a reel of RP2350 chips into your next design: today is your lucky day! Digi-Key has these chips in stock RIGHT NOW for immediate shipment. You can get a reel of either A or B type chips, with cut tape individual components coming shortly. Both types are great, but recently we've been having a lot of fun with the roomy B type (https://www.digikey.com/short/mzpjhptm), with the extra GPIO. Order today and you can start integrating the trendiest new silicon into your new PCB assembly by tomorrow afternoon.

Picture if you will, a source of energy, so radiant, that it holds the key to our energy future. The sun, a source of limitless potential, emits almost 4 octillion watts of energy every second. That's a 10 with 26 zeros behind it. If we could harness just a fraction of this power, it would be enough to meet the world's energy needs many times over.   In emerging markets like Vietnam, Malaysia, and Kenya, the race to capture the sun's energy is on. These nations recognize the transformative potential of solar power, not only for their economies but also for the health of our planet. Vietnam aims to generate 20% of its electricity from renewable sources by 2030, while Malaysia has set a target of 20% by 2025. In Kenya, the Garissa Solar Power Plant, the largest in East Africa, is already providing clean energy to thousands of homes.   But the path to a solar-powered future is not without its challenges. Efficiency in converting solar energy to electricity remains a hurdle, with current technology capturing only a portion of the sun's potential. However, advancements in materials science and energy storage hold the promise of a brighter tomorrow. As well as embedded control technologies including integrated circuits.   Imagine a world where smart energy grids, powered by the sun, provide clean, affordable electricity to every corner of the globe. A world where the very source of life on Earth also sustains our modern way of living.   How could Microchip Technology help us further embrace the boundless potential of solar power?   Links from the episode:     Guests:  Jay Nagle

“Third place”. The term originated in a 1989 book written by sociologist Ray Oldenberg. It refers to a place separate from Work or Home where humans can facilitate social interaction. The need for Third Places has grown and was extremely exacerbated by the COVID-19 global pandemic. Like many other things, the pandemic accelerated increasing trends: loneliness and obesity.   According to the World Health Organization: “High-quality social connections are essential to our mental and physical health and our well-being.” The United States Surgeon General has labeled loneliness an ‘epidemic'. The British Medical Journal published a report in late 2021 that concluded “problematic levels of loneliness are experienced by a substantial proportion of the population in many countries.”  Also according to the WHO: worldwide obesity has nearly tripled since 1975 and as late as 2016, 1.9 billion adults were overweight, of which 650 million were obese. The good news? Both of these trends are preventable and reversible. Third Places are helping to provide people with the outlet they need to improve their situation and find happiness. There is a Third Place emerging in cities across the world that solves both problems and a lot more: Community Gardens. It could be a rooftop in a densely populated city, or a common area just down the road. Community Gardens provide the benefits of “public relaxation” while also teaching the valuable skill of eating healthy. They also provide a source of STEM education for kids.   How could Microchip Technology help accelerate the growth of Third Places like Community Gardens?   Links from the episode:     Guests:  Ross Satchell  Toby Sinkinson

This week's EYE ON NPI will take you to Infinity and Beyond, with Infineon PSoC™ 4000T Microcontrollers (https://www.digikey.com/en/product-highlight/i/infineon/psoc-4000t-microcontrollers) and the CY8CPROTO-040T eval board (https://www.digikey.com/short/qhfjbt39) specifically designed to get you started with the 4000t series microcontrollers and using the Infineon-neé-Cypress CapSense technology for capacitive touch buttons and slider. The Infineon PSoC™ 4000T series of microcontrollers are based around the classic Arm Cortex M0+ core, running at 48 MHz and with 64K flash, 8K of SRAM. So, a great microcontroller for simple products/white goods that don't need USB or a graphical display, like headphones, rice cookers, tea kettles or electric toothbrushes. The chip is optimized for capacitive touch sensing, with timers and lots of capsense inputs, but not a ton of other peripherals: there's only two serial blocks that can be configured as I2C/UART/SPI, and no ADC/DAC or USB or CAN. As long as your product is intended to be low-cost, and simple, that's probably just fine! The real star of the show on these chips is the CapSense peripheral (https://www.infineon.com/cms/en/product/microcontroller/sensing-controller/capsense-controllers/capsense/), which has up to 16 inputs - out of 21 GPIO! These can be configured as "CSD-type" self-capacitance sigma-delta buttons or sliders, or as "CSX-type" mutual-capacitance X-Y grids (https://www.youtube.com/watch?v=SOOZII8cvT4). Capacitive sensing is great when you want products that react to touch without needing large and breakable tactile switches. For example, touch sensors on headphones can determine when they are inserted into the ear and when a finger is touching the body to pause or adjust volume (https://www.infineon.com/dgdl/Infineon-The_touch_sensing_HMI_in_wearable_and_IoT_devices-Whitepaper-v01_00-EN.pdf?fileId=8ac78c8c8a44f57b018a5f0711243a0f). Unlike buttons or encoders, there's no risk of eventual mechanical failure, rending a product useless: with a smooth clean surface you can still provide a full UI with low cost and maintenance. The Infineon PSoC™ 4000T series comes with the 5th generation of CapSense, which features autonomous DMA function in deep sleep, great responsivity, and moisture resistance. One downside of classic capacitive touch solutions is false 'ghost' triggering or sluggish 'touch blindness' when the touch surface is wet. This is a common issue with products that end up being used in a kitchen, bathroom, laundry room, while exercising or outside. That's because droplets of water have capacitance on the order of the human finger and so each droplet looks like a touch. Most capacitive sense implementations have a slow self-zeroing drift calibration procedure, but they don't handle sudden water sprays. CapSense 5th gen, by comparison, will maintain the same raw capacitive count even when there's spray, mist or droplets! Another neat feature is the autonomous sensing block, which allows ultra low deep sleep current of 6uA with touch-to-wake. Instead of powering up the whole core to do the capacitive touch reading and averaging in the main process thread, readings are done in a zombie mode so that we only wake up when touches are detected. If your next product design needs a reliable capacitive touch interface, the CapSense 5th gen-powered Infineon PSoC™ 4000T series (https://www.digikey.com/en/products/detail/infineon-technologies/CY8CPROTO-040T/22158824) is an excellent low-power Cortex M0+ chip that can act as the main processor of your product with high integration for a tiny BOM at an attractive price. You can get started fast by picking up a CY8CPROTO-040T eval board (https://www.digikey.com/short/j5hfb704) that has a programming/debug interface as well as button, slider and proximity sensing CapSense element. Order today and your CY8CPROTO will ship immediately, so that you can get started with your development by tomorrow afternoon!
