The STM32F373RBT6 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 128kB and 24kB 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, 16-bit sigma-delta (Σ-Δ) ADCs, two comparators, two DACs (DAC1 with 2 channels and DAC2 with 1 channel), a low-power RTC, nine general-purpose 16-bit timers, two general-purpose 32-bit timers, as well as standard and advanced communication interfaces - two I2Cs, three SPIs, three I2Ss, three USARTs, a CAN and an USB FS device.
