Overview

The STM32G081KBT6 is a high-performance 32-bit microcontroller featuring an Arm Cortex-M0+ core running at 64MHz. This device is specifically tailored for modern power management and secure applications, integrating a USB Type-C Power Delivery controller and an AES hardware encryption accelerator in a compact 32-LQFP package.

Why Choose This Part

The STM32G081KBT6 offers a high ratio of I/O to pin count, providing 30 I/Os in a 32-pin package. Its integration of specialized hardware like the USB-C PD controller and AES encryption reduces external component count and PCB footprint while maintaining low power consumption down to 1.7V operation.

Applications

USB-C Power Delivery
Utilizing the integrated UCPD controller to manage high-speed charging and power negotiation in consumer electronics.
Secure IoT Nodes
Implementing data encryption and secure communication using the on-chip AES hardware accelerator and True Random Number Generator.
Industrial Sensor Interfaces
Processing analog signals through the 12-bit ADC with hardware oversampling and dual 12-bit DACs for precise control loops.
Battery-Powered Handhelds
Leveraging multiple low-power modes, such as the 33uA shutdown mode, to extend battery life in portable devices.
