New Product Introduction

STMicroelectronics STM32U0 Series

STM32U0 - The latest generation of entry level ultra-low power MCUs

STMicroelectronics STM32U0 - front and back side of the MCU

Based on the Arm® Cortex®-M0+ core, the STM32U0 series offers high integration, reducing BoM costs and making it an attractive option for cost-conscious customers.

Offering 16 to 256 Kbytes of flash memory and 12 to 40 Kbytes of SRAM, the STM32U0 series is available in a large choice of packages (TSSOP, UQFN, LQFP, UFBGA and WLCSP) from 20 to 81 pins. Most of the packages are pin-to-pin compatible to STM32L0, STM32L1 and STM32L4.

STM32U083C-DK - Discovery kit with STM32U083MC MCU

The STM32U083C-DK Discovery kit is a complete demonstration and development platform for the STM32U083MCT6 microcontroller. It is used as a reference design for the user application development before porting to the final product.

The full range of hardware features on the board helps the user to evaluate all the peripherals (USB FS device, segment LCD, touchkey, temperature sensor, and others) and to develop applications. The ARDUINO® Uno V3, mikroBUS™, and extension connectors provide easy connection to extension shields or daughterboards for specific applications.

The STM32U083C-DK Discovery kit does not require any separate probe as it integrates the STLINK-V2EC debugger/programmer. It is operated by plugging it into a PC through a standard USB Type-A or USB Type-C® to USB Type-C® cable.
