STM32F051R8 概述

The STM32F051R8 family incorporates the high-performance ARM Cortex-M0 32-bit RISC core operating at a 48 MHz frequency, high-speed embedded memories (Flash memory up to 64 Kbytes and SRAM up to 8 Kbytes), and an extensive range of enhanced peripherals and I/Os. All devices offer standard communication interfaces (up to two I2Cs, two SPIs, one I2S, one HDMI CEC, and up to two USARTs), one 12-bit ADC, one 12-bit DAC, up to five general-purpose 16-bit timers, a 32-bit timer and an advanced-control PWM timer.

The STM32F051R8 family operates in the -40 to +85 C and -40 to +105 C temperature ranges, from a 2.0 to 3.6 V power supply. A comprehensive set of power-saving modes allows the design of low-power applications.
