STM32G474RET3

STM32G474RET3 is a general-purpose, Arm-based 32-bit microcontroller. The Cortex-M4 core features a single-precision floating-point unit (FPU), which supports all the Arm single-precision data-processing instructions and all the data types. It also implements a full set of DSP (digital signal processing) instructions and a memory protection unit (MPU), which enhances the application’s security. The device also embeds several protection mechanisms for embedded Flash memory and SRAM: readout protection, write protection, secure memory area and proprietary code readout protection. The device embeds peripherals, allowing mathematical/arithmetic function acceleration (CORDIC for trigonometric functions and FMAC unit for filter functions).
