STM32G473CET6 Description

The STM32G473xB/xC/xE devices are built around the powerful 32-bit RISC Arm? Cortex?-M4 core. They function at up to 170 MHz of frequency. All of the Arm single-precision data-processing commands and all data types are supported by the Cortex-M4 core's single-precision floating-point unit (FPU). Additionally, a memory protection unit (MPU) and a full set of DSP (digital signal processing) instructions are implemented, which improves the security of the application.

These devices include high-speed memories, including up to 512 Kbytes of Flash memory and 128 Kbytes of SRAM, a flexible external memory controller (FSMC) for static memories (for devices with packages of 100 pins and more), a Quad-SPI Flash memory interface, and a wide variety of enhanced I/Os and peripherals connected to two APB buses, two AHB buses, and a 32-bit multi-AHB bus matrix.
