描述 Description

The STM32F051xx microcontrollers incorporate the high-performance ARM? Cortex?-M0 32-bit RISC core operating at up to 48 MHz frequency, high-speed embedded memories (up to 64 Kbytes of Flash memory and 8 Kbytes of SRAM), and an extensive range of enhanced peripherals and I/Os. All devices offer standard communication interfaces (up to two I2Cs, up to two SPIs, one I2S, one HDMI CEC and up to two USARTs), one 12-bit ADC, one 12-bit DAC, six 16-bit timers, one 32-bit timer and an advanced-control PWM timer.
