Description
The STM32F103xC, STM32F103xD and STM32F103xE performance line family
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 512 Kbytes and
SRAM up to 64 Kbytes), and an extensive range of enhanced I/Os and peripherals
connected to two APB buses. All devices offer three 12-bit ADCs, four general purpose 16-
bit timers plus two PWM timer, as well as standard and advanced communication interfaces:
up to two I
2
Cs, three SPIs, two I2Ss, one SDIO, five USARTs, an USB and a CAN.
The STM32F103xx High-density performance line family operates in the
