STMicroelectronics STM32L552
STM32L552 variants from STMicroelectronics
STM32L552 Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
Key Features
- Footprint / package: 64-LQFPSingle package option across listed variants; still confirm reel vs tube suffix if you auto-insert.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
Target Applications
- Microcontrollers — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained
Product Details
Compare 1 STM32L552 part number by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.

How to Choose the Right STM32L552 Microcontrollers
Match the footprint first
Packages here: 64-LQFP. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For STM32L552, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "STM32L552" — include the full suffix (e.g. RET6Q). RFQ with reel/tube preference and required date code.
