STM32F051R8H6 Description
The STM32F051xx microcontrollers incorporate the high-performance ARM? Cortex?-M032-bit RISC core operating at up to 48 MHz frequency, high-speed embedded memories (upto 64 Kbytes of Flash memory and 8 Kbytes of SRAM), and an extensive range of enhancedperipherals 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-bitDAC, six 16-bit timers, one 32-bit timer and an advanced-control PWM timer.The STM32F051xx microcontrollers operate in the -40 to +85 °C and -40 to +105 °Ctemperature ranges, from a 2.0 to 3.6 V power supply. A comprehensive set of powersaving modes allows the design of low-power applications.
