Description

General part information

STM32U031K8 Series

The STM32U031x4/6/8 devices are ultra-low-power microcontrollers based on the high-performance Arm®Cortex®-M0+ 32-bit RISC core operating at a frequency of up to 56 MHz.

The STM32U031x4/6/8 devices embed high-speed memories (up to 64-Kbyte flash memory and 12-Kbyte SRAM with hardware parity check), and an extensive range of enhanced I/Os and peripherals connected to APB and AHB buses, and a 32-bit multi-AHB bus matrix.

They also embed protection mechanisms for embedded flash memory and SRAM, such as readout protection and write protection.
