ARM®Cortex®-M4F microcontroller, 32-bit, 2-3.6V, 128KB, LQFP-32

Description
The STM32G431xx is based on the powerful Arm® Cortex®-M4 32-bit RISC core.
The Cortex®-M4 core has a single-precision FPU that supports all precision data processing instructions from Arm as well as all other data types. A complete set of DSP instructions and an MPU are implemented.
Integrated high-speed memory (128-kB Flash and 32-kB SRAM), plus a whole host of I/Os + peripherals that are connected to 2 APB buses, 2 AHB buses and 1x 32-Bit multi-AHB bus matrix.
Built-in protection for embedded flash memory and SRAM.
The devices include peripherals that speed up functionality based on mathematics/arithmetic.
- 2x 12-Bit ADCs
- 4x comparators
- 3x operational amplifiers
- 4x DAC channels
- 1x voltage reference buffer
- 1x RTC
- 1x 32-Bit timer
- 2x 16-Bit PWM timers
- 7x 16-Bit timers
- 1x 16-Bit low-power timer
- 3x I2Cs
- 3x multiplexed SPIs with two half-duplex I2Ss
- 3 USARTs, 1x UART + 1x Low-power UART.
