The STM32F051R8T7 is an entry level STM32 F0 series 32-bit Microcontroller incorporates the high-performance ARM Cortex-M0 RISC core operating at a 48MHz frequency, high speed embedded memories (Flash memory up to 64kB and SRAM up to 8KB) and an extensive range of enhanced peripherals and I/Os. This device offer standard communication interfaces (two I²Cs, two SPIs, one I²S, one HDMI CEC and two USARTs), one 12-bit ADC, one 12-bit DAC, six 16-bit timers, one 32-bit timer and an advanced control PWM timer.
