STM32G081GBU6

Overview

The STM32G081GBU6 is a mainstream Arm Cortex-M0+ microcontroller operating at 64 MHz with 128 Kbytes of Flash and 36 Kbytes of RAM. It features integrated hardware security features including an AES-256 encryption engine to protect sensitive data and firmware.

Why Choose This Part

This MCU provides a high ratio of RAM and Flash to its physical pin count, allowing for complex firmware in space-constrained designs. It simplifies power architecture with a single power supply and reduces external component count through internal RC oscillators and integrated security hardware.

Applications

Getting Started

Development is best supported by the STM32CubeG0 software package and the STM32CubeIDE. For hardware evaluation, engineers can use the NUCLEO-G071RB or the STM32G081B-EVAL board to test firmware before moving to the UFQFPN28 package.
