The STM32F301R8T6 is a STM32 F3 series 32-bit Microcontroller incorporates the high-performance ARM Cortex-M4 RISC core operating at a frequency of up to 72MHz and embedding a floating point unit (FPU), high-speed embedded memories (Flash memory up to 64kB and 16kB of SRAM) and an extensive range of enhanced I/Os and peripherals connected to two APB buses. The device offer a fast 12-bit ADCs, three comparators, an operational amplifier, up to 18 capacitive sensing channels, one DAC channel, a low-power RTC, one general-purpose 32-bit timer, one timer dedicated to motor control and up to three general-purpose 16-bit timers and one timer to drive the DAC, as well as standard and advanced communication interfaces - three I²Cs, two SPIs with multiplexed full-duplex I²S and three USARTs.
