Product Summary

The STM32F103C8T6 medium-density performance line 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 128 Kbytes and SRAM up to 20 Kbytes), and an extensive range of enhanced I/Os and peripherals connected to two APB buses. The STM32F103C8T6 offers 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. The STM32F103C8T6 medium-density performance line includes devices in six different package types: from 36 pins to 100 pins.
