STM32G Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
STM32G is a STMicroelectronics order-code family — not a single orderable MPN. This page lists 88 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.
Mainstream Value-Line Arm Cortex-M0+ MCU with 32 Kbytes of of Flash memory memory, 8 Kbytes RAM, 64 MHz CPU, 2x USART, timers, ADC, comm. I/F, 2-3.6V Other listed variants describe: Arm Cortex-M0+ MCU | 32KB Flash | 8KB RAM | 64MHz | 2xUSART | ADC; Mainstream Value-Line Arm Cortex-M0+ MCU with 64 Kbytes of of Flash memory memory, 8 Kbytes RAM, 64 MHz CPU, 2x USART, timers, ADC, comm. I/F, 2-3.6V.
Across listed variants, watch these parameters: packages: 20-TSSOP (0.173, 4.40mm Width), 28-UFQFN, 32-UFQFN Exposed Pad, 48-LQFP, 32-LQFP (+2 more).
Suffix examples in this family: 030C6T6, 030C6T6TR, 030C8T6TR, 030F6P6, 030K6T6TR, 030K8T6TR, 031C6T6, 031C8U6. 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: STM32G030C6T6, STM32G030C6T6TR, STM32G030C8T6TR, STM32G030F6P6, STM32G030K6T6TR, STM32G030K8T6TR.
Key Features
- Footprint / package: 20-TSSOP (0.173, 4.40mm Width), 28-UFQFN, 32-UFQFN Exposed Pad, 48-LQFP (+3 more)Land pattern and thermal pad differ between these packages — run a quick footprint check before you swap variants.

- 88 distinct suffix patternsExamples: 030C6T6, 030C6T6TR, 030C8T6TR, 030F6P6, 030K6T6TR (+83 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 STM32G map to package, grade, and reel options.
STM32G 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: 030C6T6, 030C6T6TR, 030C8T6TR, 030F6P6, 030K6T6TR, 030K8T6TR, 031C6T6, 031C8U6, 031F4P6TR, 031F6P6 (+78 more).
What changes between rows: Package Type. Sort the table by these columns when narrowing from base number to a single MPN.
Full MPN examples: STM32G030C6T6, STM32G030C6T6TR, STM32G030C8T6TR, STM32G030F6P6, STM32G030K6T6TR.
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 STM32G Microcontrollers
Match the footprint first
Packages here: 20-TSSOP (0.173, 4.40mm Width), 28-UFQFN, 32-UFQFN Exposed Pad, 48-LQFP (+3 more). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For STM32G, 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 "STM32G" — include the full suffix (e.g. 030C6T6, 030C6T6TR, 030C8T6TR). RFQ with reel/tube preference and required date code.
