Microchip Technology has announced a 32bit 200MHz version of its dsPIC33 series of DSP-heavy MCUs. dsPIC33A, as the family will be called, is aimed at fast closed-loop control of PSUs and motors. As with earlier dsPIC processors, the parts remain a combination of CPU and maths accelerator (‘DSP engine’), rather than a pure DSP architecture. In this fifth generation, the ...

Slightly fiddly-to-find ATtiny412 information
The delightful 8pin ATtiny412 comes in a few versions, all with 4kbyte of flash and 256byte of ram, and it takes a while to dig out the following: ATtiny412-SSNR 20MHz 1.8-5.5V -40 to +105°C tape and reel ATtiny412-SSN tube or tray ATtiny412-SSFR 16MHz 2.7-5.5V -40 to +125°C tape and reel ATtiny412-SSF tube or tray
Microchip goes 64bit with RISC-V, and plans Arm
Microchip has announced its first 64bit processors, picking the RISC-V instruction set for the initial parts: an octa-core for space and a industrial quad-core. Although, “future PIC64 families will include devices based on RISC-V or Arm architectures”, said the company. PIC64-HPSC is the family name of the space processors, which have come out of a 2022 deal with NASA to ...
PCIM: Microchip’s SiC bi-directional on-board charger design for EVs
Microchip has turned to silicon carbide to create a bi-directional electric vehicle on-board charger design for 400V or 800V batteries. There are two halves: a 7.6kW bi-directional two-phase interleaved totem-pole power factor corrector, and an 11kW dual full bridge transformer-coupled bi-directional dc-dc converter. “These two designs work together,” Microchip told Electronics Weekly. “At PCIM we showed both operating in bi-directional ...
Embedded World: AVR MCU gets USB and code protection
Microchip has created an AVR microcontroller series with 12Mbit/s USB 2.0 and code protection. “As the next generation of Microchip 8-bit MCUs to integrate USB connectivity, the AVR DU family is designed to provide enhanced security features,” said the company. Protection comes from permanently disabling write capability within the programming and debug interface after initial programming, and handing over update ...
Dev kit for space-qualified FPGAs with QML qualification
Microchip is aiming at satellite designers with a development kit built around its radiation tolerant RT PolarFire FPGAs, for which MIL-STD-883 Class B qualification has been gained and both Class Q and Class V qualification have been sought. October 2023 update: RT PolarFire FPGA’s are now QML (qualified manufacturers list) Class Q qualified, as designated by the US Defense Logistics ...
Reclocker redriver IC for USB 3.2 over 15m cables
Microchip has created a set of dual-channel single-lane USB 3.2 Gen1 SuperSpeed reclocker redriver ICs for automotive and industrial cables up to 15m long. “Adding electronic components to applications across automotive, industrial and consumer industries has spurred the need for far-reaching USB cabling products,” according to the company. EQCO510 is the automotive version, qualified to AEC-Q100 Grade 2 and operates ...
PCIM: SiC automotive e-fuse demo disconnects up to 30A 900V
Microchip has used silicon carbide power transistors in an electronic fuses demonstrator for electric vehicle batteries. “The demonstrator can detect and interrupt fault currents in microseconds, 100 – 500 times faster than traditional mechanical approaches,” according to the company. “The fast response substantially reduces peak short-circuit currents from tens of kilo-amps to hundreds of amps, which can prevent a fault ...
Hybrid power modules for more-electric aircraft start at 5kVA
Microchip has announced a range of integrated power modules for applications including more-electric aircraft (MEA). Output power rating starts at 5kVA. Little hard information is yet available, but the company has said there will be 12 variants with either silicon carbide mosfets or IGBTs. One possible configuration “The configurable power devices include a three-bridge topology that is available in SiC ...
Microchip’s 2nd gen smart meter MCUs
Microchip is aiming at smart metering with a family of microcontrollers and a power-line communication modem IC. The processors, nominally the PIC32CXMT family, have one or two Arm Cortex-M4F cores – all get a 200MHz application processor, and some get a 240MHz metrology processing core. The PIC32CXMTSH version in particular (see diagram) gets an ‘energy metering analogue front-end’ (EMAFE) as ...
