STM32F071V8T6  Description

The STM32F071x8/xB 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 128 Kbytes of Flash memory and 16 Kbytes of SRAM), and an extensive range of enhanced peripherals and I/Os. All devices offer standard communication interfaces (two I2Cs, two SPI/one I2S, one HDMI CEC, and four USARTs), one 12-bit ADC, one 12-bit DAC with two channels, seven 16-bit timers, one 32-bit timer, and an advanced-control PWM timer.
