Product details

The STM32L052K8U6D is an STMicroelectronics ultra-low-power 32-bit MCU built around the ARM Cortex-M0+ core running at 32 MHz. The part belongs to the STM32L0 series, ST's entry-level energy-efficient family aimed at battery-powered, portable, and industrial sensor nodes where every microamp matters.

Package and footprint — the 32-UFQFPN with exposed pad

Housed in a 32-UFQFN Exposed Pad package (supplier device package 32-UFQFPN, 5x5 mm), this is a compact, surface-mount device with a thermal pad underneath. The 27 general-purpose I/O pins are enough for a sensor hub or a small control panel with a few buttons, LEDs, and a serial interface.

On-chip analog and connectivity

The internal oscillator keeps the clock tree simple for many applications.

Frequently asked questions

What is the difference between STM32L052K8U6 and STM32L052K8U6D?

The 'D' suffix typically denotes a specific shipping or packing variant — often tray versus tape-and-reel, or a minor revision. The core silicon (die, memory, peripherals) is identical. For exact differences, the ST datasheet's ordering information table is the final word, but functionally they are the same MCU.

What is the operating frequency of STM32L052K8U6D?

The core runs at 32 MHz, which is the standard speed grade for the STM32L0 series Cortex-M0+ parts.
