Microchip’s first ARM processor with cryptographic engine

In Production The CEC1302 incorporates a high-performance 32-bit ARM® Cortex®-M4 embedded microcontroller with 128 Kilobytes of SRAM and 32 Kilobytes of Boot ROM. It communicates with the system host using the I2C bus. The CEC1302 has two SPI memory interfaces that allow the EC to read its code from external SPI flash memory: private SPI and/or shared SPI. The Shared SPI interface allows for EC code to be s ...

Getting Started with OPENOCD Using FT2232H Adapter for SWD Debugging

Old MCUs from vendors like ATMEL and MICROCHIP, like the PIC16F and Atmega family, tend to have a special programming interface to program internal flash. For example, Atmega used SPI pins (MISO, MOSI, SCK) and PIC used two pins (PGC, PGD)— one as a clock and another as a bi-directional data line. New MCUs, especially with an ARM core, use JTAG/SWD as a programming/debugging interface. What is the differenc ...
