Product details

Package and mounting

The STM32L031C6U6TR: It targets battery-operated and energy-harvesting designs where every microamp matters — the L0 family's dynamic and stop-mode currents are class-leading for a 32-bit core at this speed.

Memory and peripheral fit for a code-constrained BOM

1 KB hardware EEPROM (1K x 8) stores calibration constants without wear-leveling overhead. 38 I/O in the 48-UFQFN package handle a parallel display bus plus sensors and actuators.

Package and footprint — 48-UFQFN with exposed pad

48-UFQFN Exposed Pad package (7x7 mm body, supplier device package 48-UFQFPN). Tape & Reel (TR) packaging.

Frequently asked questions

What is the difference between STM32L031C6U6 and STM32L031C6U6TR?

The suffix "TR" denotes Tape & Reel packaging, while the base part number STM32L031C6U6 (without the TR suffix) typically ships in tray or tube format. The silicon, package, and electrical specifications are identical. The TR variant is intended for automated assembly lines that feed from reels.

Can STM32L031C6U6TR be used as a replacement for STM32L031C6U6?

Yes — the STM32L031C6U6TR is functionally identical to the STM32L031C6U6. The only difference is the shipping medium (Tape & Reel vs. tray/tube). If your assembly process accepts reels, it is a direct drop-in replacement.
