STM32C Overview

What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.

Key Features

Footprint / package: 20-TSSOP (0.173", 4.40mm Width), 28-UFQFNLand pattern and thermal pad differ between these packages — run a quick footprint check before you swap variants.
Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
10 distinct suffix patternsExamples: 011F4P6, 011F4P6TR, 011F4U6TR, 011F6P6, 011F6P6TR (+5 more). Decode suffix meaning in the ordering notes under the variant table.

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

How suffixes on STM32C map to package, grade, and reel options.

How to Choose the Right STM32C Microcontrollers

📦

Match the footprint first

Packages here: 20-TSSOP (0.173", 4.40mm Width), 28-UFQFN. Open the land-pattern drawing before you substitute a different suffix.

⚡

Electrical headroom

Compare voltage and current columns in the variant table. For STM32C, 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 "STM32C" — include the full suffix (e.g. 011F4P6, 011F4P6TR, 011F4U6TR). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the STM32C product family.

Is STM32C a single part I can order, or a family prefix?

STM32C is a base / family code from STMicroelectronics. You order a full MPN such as STM32C011F4P6, STM32C011F4P6TR, STM32C011F4U6TR. The variant table lists 10 orderable lines with different suffixes.

What do the suffix letters on STM32C part numbers mean?

Listed suffix fragments include: 011F4P6, 011F4P6TR, 011F4U6TR, 011F6P6, 011F6P6TR, 011F6U6TR. Typically they encode package (20-TSSOP (0.173", 4.40mm Width), 28-UFQFN), temperature grade, and tape/reel option. Always decode on the STMicroelectronics datasheet ordering guide — do not guess from pattern alone.

Which specs actually differ between STM32C variants here?

On this page the varying fields are: Package Type. Filter the table by the parameter you care about before picking an MPN.

Can I swap between 20-TSSOP (0.173", 4.40mm Width), 28-UFQFN packages in the same STM32C family?

Only after footprint and thermal review. Packages listed here (20-TSSOP (0.173", 4.40mm Width), 28-UFQFN) use different land patterns and often different thermal resistance. Layout swaps need a new paste stencil at minimum, not just a BOM edit.

What is the lifecycle status of STM32C variants?

Lifecycle values in our listing: Active. Status is per MPN suffix — one variant can be Active while another is NRND. Check PCN for your exact suffix before multi-year commitments.

What should I send for an RFQ on STM32C?

Full manufacturer MPN (not just STM32C), quantity, needed date code, reel vs tube, and any compliance docs (CoC, RoHS, conflict minerals). If you only know the base prefix, include a photo of the existing label or reel.
