ARM®Cortex®-M4F microcontroller, 32-bit, 2-3.6V, 512KB, LQFP-48

Description
The STM32G474xx is based on the powerful Arm® Cortex®-M4 32-bit RISC core.
The Cortex-M4 core has a single-precision FPU that supports all single-precision data processing instructions from the Arm as well as all other data types. A complete set of DSP instructions and an MPU are implemented.
Integrated high-speed memory (512-KB Flash and 128-KB SRAM), plus FSMC and Quad SPI Flash interface 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.
