The chip seen just above the center of this image is an ARM Cortex-M3. It provides the ability to interface and program the main chip on the STM32F3 Discovery board. The protocol used is the ST ...

The core of this board is the tiny WinnerMicro W600 MCU, which integrates a 32-bit ARM Cortex M3 CPU, along with dual UARTs, I2C, SPI and I2S interfaces, as well as a real-time clock (RTC).

The Fujitsu FM3 devices, which are built around the ARM® Cortex™-M3 global-standard core, incorporate a wide variety of peripheral features refined during Fujitsu’s years of experience developing its ...
