Description

STM32G431KBT6 is a 32-bit microcontroller with ARM Cortex-M4 core from STMicroelectronics. The G4 series has been optimized in terms of value for money, so that the G4 family microcontrollers can be used for both small projects and devices requiring more resources. The STM32G431KBT6 chip offers memory protection unit (MPU), fast embedded memories (128 KB Flash and 32 KB SRAM), DMA and a wide range of system functions, improved I/O and peripherals. Standard communication interfaces (I2C, SPI/I2S and USART) are available, one 12-bit ADC with 11 channels, low power RTC, advanced PWM control clock, 16-bit clocks, two basic two watchdog clocks and SysTick timer.
