Texas Instruments MSP430FG
MSP430FG variants from Texas Instruments
MSP430FG Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
MSP430FG is a Texas Instruments order-code family — not a single orderable MPN. This page lists 15 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.
16-bit 8MHz MCU, 16KB FLASH, 256B SRAM, 16-bit ADC, LCD, 48-SSOP Other listed variants describe: 16-bit MCU, 8MHz, 16KB FLASH, 256B SRAM, 48-VQFN; 16-bit MCU, 8MHz, 16KB Flash, 256B SRAM, 32 I/O, 48-VQFN.
Suffix examples in this family: 4250IDLR, 4250IRGZR, 4250IRGZT, 4260IDLR, 4260IRGZR, 4270IDLR, 4270IRGZR, 4270IRGZT. 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: MSP430FG4250IDLR, MSP430FG4250IRGZR, MSP430FG4250IRGZT, MSP430FG4260IDLR, MSP430FG4260IRGZR, MSP430FG4270IDLR.
Key Features
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 15 distinct suffix patternsExamples: 4250IDLR, 4250IRGZR, 4250IRGZT, 4260IDLR, 4260IRGZR (+10 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 MSP430FG map to package, grade, and reel options.
MSP430FG 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: 4250IDLR, 4250IRGZR, 4250IRGZT, 4260IDLR, 4260IRGZR, 4270IDLR, 4270IRGZR, 4270IRGZT, 437IPN, 438IPN (+5 more).
Full MPN examples: MSP430FG4250IDLR, MSP430FG4250IRGZR, MSP430FG4250IRGZT, MSP430FG4260IDLR, MSP430FG4260IRGZR.
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 MSP430FG 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 MSP430FG, 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 "MSP430FG" — include the full suffix (e.g. 4250IDLR, 4250IRGZR, 4250IRGZT). RFQ with reel/tube preference and required date code.
