Product Description:

The FT32F103x8/B uses a high-performance ARM Cortex-M3 32-bit RISC core operating at up to 72 MHz, with built-in high-speed memory (up to 128K bytes of Flash and 20K bytes of SRAM) and a rich set of enhanced I/O ports. The chip provides a rich set of peripherals including two I2C interfaces, two SPI interfaces, three USART interfaces, one USB interface, one CAN, two 12-bit ADCs, and up to seven timers (one advanced, three general-purpose, two watchdogs, and one system). Three low-power modes ensure the requirements of low-power applications. Support SWD and JTAG interface debugging, 2 observation points as well as 6 hardware breakpoints for user-friendly debugging.
