Product Summary

The STM32F103C8T6 is a performance line, ARM-based 32-bit MCU with flash, USB, CAN, seven 16-bit timers. It incorporates the high-performance ARM Cortex-M3 32-bit RISC core operating at a 72 MHz frequency, high-speed embedded memories (Flash memory up to 128Kbytes and SRAM up to 20 Kbytes), and an extensive range of enhanced I/Os and pe ripherals connected to two APB buses. All devices offer two 12-bit ADCs, three general purpose 16 bit timers plus one PWM timer, as well as standard and advanced communication interfaces: up to two I2Cs and SPIs, three USARTs, an USB and a CAN.
