Description

General part information

NUCLEO-G491RE Series

The STM32G491xC/xE devices are based on the high-performance Arm®Cortex®-M4 32-bit RISC core. They operate at a frequency of up to 170 MHz.

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.

These devices embed high-speed memories (up to 512 Kbytes of flash memory, and 112 Kbytes of SRAM), a Quad-SPI flash memory interface, an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix.
