Texas Instruments MSP430FE
MSP430FE variants from Texas Instruments
MSP430FE Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
Key Features
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 13 distinct suffix patternsExamples: 4232IPMR, 423AIPMR, 423IPM, 423IPMR, 4242IPM (+8 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 MSP430FE map to package, grade, and reel options.
How to Choose the Right MSP430FE Microcontrollers
Match the footprint first
Pull the exact package drawing for your MPN — base-number swaps fail most often at the footprint, not the schematic.
Electrical headroom
Compare voltage and current columns in the variant table. For MSP430FE, 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 "MSP430FE" — include the full suffix (e.g. 4232IPMR, 423AIPMR, 423IPM). RFQ with reel/tube preference and required date code.
