STMicroelectronics STM32C
STM32C variants from STMicroelectronics
STM32C Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
STM32C is a STMicroelectronics order-code family — not a single orderable MPN. This page lists 10 variants that share the same core device but differ in suffix fields (package, grade, reel/tube, electrical bin, etc.). Pick the exact full part number; substituting within the family without checking the datasheet often causes assembly or spec mismatches.
IC MCU 32BIT 16KB FLASH 20TSSOP Other listed variants describe: IC MCU 32BIT 16KB FLASH 20UFQFPN; IC MCU 32BIT 32KB FLASH 20TSSOP.
Across listed variants, watch these parameters: packages: 20-TSSOP (0.173", 4.40mm Width), 28-UFQFN.
Suffix examples in this family: 011F4P6, 011F4P6TR, 011F4U6TR, 011F6P6, 011F6P6TR, 011F6U6TR, 011J6M6, 031C6T6. The characters after the base number usually encode package, temperature, or performance grade — compare the variant table column-by-column rather than assuming pin-compatible drops-in.
Columns that actually vary on this page: Package Type. If two rows match on MPN prefix but differ there, they are not interchangeable for production.
Example MPNs: STM32C011F4P6, STM32C011F4P6TR, STM32C011F4U6TR, STM32C011F6P6, STM32C011F6P6TR, STM32C011F6U6TR.
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

Ordering Code Differences
How suffixes on STM32C map to package, grade, and reel options.
STM32C uses a shared prefix; characters after the prefix encode orderable options. Two lines with the same prefix are not drop-in replacements unless the differing columns match your need.
Suffixes seen here: 011F4P6, 011F4P6TR, 011F4U6TR, 011F6P6, 011F6P6TR, 011F6U6TR, 011J6M6, 031C6T6, 031G6U6TR, 031K6T6.
What changes between rows: Package Type. Sort the table by these columns when narrowing from base number to a single MPN.
Full MPN examples: STM32C011F4P6, STM32C011F4P6TR, STM32C011F4U6TR, STM32C011F6P6, STM32C011F6P6TR.
Tip: photograph or copy the reel label — reel diameter, QTY per reel, and moisture sensitivity level (MSL) are often suffix-driven and won't show in the schematic.
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.
