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.
MSP430FE is a Texas Instruments order-code family — not a single orderable MPN. This page lists 13 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.
8MHz 16-bit MCU, 2x 12-bit ADC, 8KB Flash, 256B RAM, LQFP Other listed variants describe: 8MHz MSP430 MCU, 3x 16b Sigma-Delta ADC, 8KB Flash, 256B RAM, LQFP; 8MHz 16-bit MCU, 3x 16-bit ADC, 8KB Flash, 256B RAM, LQFP.
Suffix examples in this family: 4232IPMR, 423AIPMR, 423IPM, 423IPMR, 4242IPM, 4242IPMR, 4252IPM, 425IPM. 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.
Example MPNs: MSP430FE4232IPMR, MSP430FE423AIPMR, MSP430FE423IPM, MSP430FE423IPMR, MSP430FE4242IPM, MSP430FE4242IPMR.
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.
MSP430FE 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: 4232IPMR, 423AIPMR, 423IPM, 423IPMR, 4242IPM, 4242IPMR, 4252IPM, 425IPM, 4272IPM, 4272IPMR (+3 more).
Full MPN examples: MSP430FE4232IPMR, MSP430FE423AIPMR, MSP430FE423IPM, MSP430FE423IPMR, MSP430FE4242IPM.
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 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.
