STM32G431C6T6                 Description

The STM32G431x6/x8/xB device is based on a high-performance ARM Cortex - M4 32-bit RISC core. They operate at frequencies as high as 170 MHz. The Cortex-M4 kernel uses a single-precision floating-point unit (FPU) and supports all ARM single-precision data processing instructions and all data types. It also implements a complete set of DSP (Digital signal processing) instructions and a memory protection unit (MPU) that enhances application security. These devices include high-speed memory (up to 128K bytes of flash memory and 32K bytes of SRAM), a wide range of enhanced I Band O, and peripherals connected to two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix. These devices also embed several protection mechanisms for embedded flash memory and SRAM: read protection, write protection, secure storage area, and proprietary code read protection.
