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 ...

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 ...

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 ...

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 ...

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 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 ...

Microchip has expunged some of the tricky bits of system design with its ARM926EJ-S based SAM9X60 MPU, by introducing a system-on-module that pre-pairs the processor with 1Gbit of DDR2 dram, a 4Gbit of NAND flash and 1kbit of serial eeprom – on top of the chip’s own 64kbyte of internal sram. Actually built around a 600MHz SAM9X60D1G, and called SAM9X60D1G-SOM, ...

Microchip has announced a cyber-attack-resilient microcontroller family for securing end-user equipment that goes “beyond NIST 800-193 Platform Firmware Resiliency guidelines with run-time firmware protection that anchors the secure boot process while establishing an entire chain-of-trust for the system”, according to the company, adding that it is also designed for Open Compute Project Security Called CEC173x, the aim is to be a real-time root-of-trust ...

Microchip is to introduce five families of 8bit microcontrollers, sharing both its PIC and ex-Atmel AVR resources amongst new PICs and AVRs. Users who favour PIC or AVR should not be concerned, according to Microchip marketing director Oyvind Strom: “We are maintaining the bus structures of PIC and AVR, the way you interact with the peripherals and the pin-outs,” he told ...

Microchip is offering a 28Vin space-grade dc-dc converter built from discrete components. Why discrete components and not hybrid construction? “They are easier to customize than alternative space-grade power converters so they can meet specific voltage, current and other needs,” said Microchip v-p of discrete products Leon Gross. Custom versions are available “with reasonable lead time and modest NRE cost,” said ...
