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. - 1x FDCAN - 1x SAI - USB device - UCPD Supports some independent power supplies, including an analogue independent supply input for ADC, DAC, OPAMPs and comparators. A VBAT input enables the user to back up the RTC and the register. https://elecena.pl/product/17879431/stm32g431rbt6-arm-cortex-m4f-microcontroller-32-bit-2-3-6v-128kb-lqfp-64 2021-04-26 https://elecena.pl/product/17879431/stm32g431rbt6-arm-cortex-m4f-microcontroller-32-bit-2-3-6v-128kb-lqfp-64 2022-10-06 https://elecena.pl/product/17879431/stm32g431rbt6-arm-cortex-m4f-microcontroller-32-bit-2-3-6v-128kb-lqfp-64 2022-11-14 https://elecena.pl/product/17879431/stm32g431rbt6-arm-cortex-m4f-microcontroller-32-bit-2-3-6v-128kb-lqfp-64 2023-01-06 https://elecena.pl/product/17879431/stm32g431rbt6-arm-cortex-m4f-microcontroller-32-bit-2-3-6v-128kb-lqfp-64 2023-12-09 https://elecena.pl/product/17879431/stm32g431rbt6-arm-cortex-m4f-microcontroller-32-bit-2-3-6v-128kb-lqfp-64 2024-03-23 https://elecena.pl/product/17879431/stm32g431rbt6-arm-cortex-m4f-microcontroller-32-bit-2-3-6v-128kb-lqfp-64 2024-04-25 https://elecena.pl/product/17879431/stm32g431rbt6-arm-cortex-m4f-microcontroller-32-bit-2-3-6v-128kb-lqfp-64 2024-07-14 https://elecena.pl/product/17879431/stm32g431rbt6-arm-cortex-m4f-microcontroller-32-bit-2-3-6v-128kb-lqfp-64 2025-12-12 https://elecena.pl/product/17879431/stm32g431rbt6-arm-cortex-m4f-microcontroller-32-bit-2-3-6v-128kb-lqfp-64 2026-01-17
