Description
The STM32F103xx 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 128Kbytes and SRAM up to 20 Kbytes), and an extensive
range of enhanced I/Os and peripherals 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 I
