STM32F103CBU6 Datasheet PDF - ST Microelectronics

The STM32F103CBU6 is a medium density performance line STM32 F1 series 32-bit Microcontroller incorporates the high-performance ARM Cortex-M3 RISC core operating at a 72MHz frequency, high speed embedded memories (Flash memory up to 128kB and SRAM up to 20KB) and an extensive range of enhanced peripherals and I/Os connected to two APB buses. This device offer two 12-bit ADCs, three general purpose 16-bit timers plus one PWM timer, as well as standard communication interfaces - up to two I²Cs, two SPIs, three USARTs, an USB and a CAN.
