MSP430G Overview

What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.

MSP430G is a Texas Instruments order-code family — not a single orderable MPN. This page lists 97 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.

16MHz 16b MCU, 0.5KB FLASH, 128B SRAM, 10 GPIO, 1 Timer, VQFN Other listed variants describe: 16MHz 16-bit MCU, 1KB FLASH, 128B SRAM, 10 GPIO, VQFN; 16MHz 16-Bit MCU, 1KB FLASH, 128B SRAM, SPI/I2C, 20-TSSOP.

Across listed variants, watch these parameters: packages: 14-TSSOP (0.173", 4.40mm Width), 20-TSSOP (0.173", 4.40mm Width), 16-VQFN Exposed Pad, 32-VFQFN Exposed Pad.

Suffix examples in this family: 2001IRSA16T, 2101IRSA16R, 2101IRSA16T, 2102IPW20, 2102IPW20R, 2111IRSA16R, 2111IRSA16T, 2112IRSA16T. 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: MSP430G2001IRSA16T, MSP430G2101IRSA16R, MSP430G2101IRSA16T, MSP430G2102IPW20, MSP430G2102IPW20R, MSP430G2111IRSA16R.

Ordering Code Differences

How suffixes on MSP430G map to package, grade, and reel options.

MSP430G 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: 2001IRSA16T, 2101IRSA16R, 2101IRSA16T, 2102IPW20, 2102IPW20R, 2111IRSA16R, 2111IRSA16T, 2112IRSA16T, 2121IN14, 2121IPW14R (+87 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: MSP430G2001IRSA16T, MSP430G2101IRSA16R, MSP430G2101IRSA16T, MSP430G2102IPW20, MSP430G2102IPW20R.

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 MSP430G Microcontrollers

📦

Match the footprint first

Packages here: 14-TSSOP (0.173", 4.40mm Width), 20-TSSOP (0.173", 4.40mm Width), 16-VQFN Exposed Pad, 32-VFQFN Exposed Pad. Open the land-pattern drawing before you substitute a different suffix.

⚡

Electrical headroom

Compare voltage and current columns in the variant table. For MSP430G, 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 "MSP430G" — include the full suffix (e.g. 2001IRSA16T, 2101IRSA16R, 2101IRSA16T). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the MSP430G product family.

Is MSP430G a single part I can order, or a family prefix?

MSP430G is a base / family code from Texas Instruments. You order a full MPN such as MSP430G2001IRSA16T, MSP430G2101IRSA16R, MSP430G2101IRSA16T. The variant table lists 97 orderable lines with different suffixes.

What do the suffix letters on MSP430G part numbers mean?

Listed suffix fragments include: 2001IRSA16T, 2101IRSA16R, 2101IRSA16T, 2102IPW20, 2102IPW20R, 2111IRSA16R. Typically they encode package (14-TSSOP (0.173", 4.40mm Width), 20-TSSOP (0.173", 4.40mm Width), 16-VQFN Exposed Pad, 32-VFQFN Exposed Pad), temperature grade, and tape/reel option. Always decode on the Texas Instruments datasheet ordering guide — do not guess from pattern alone.

Which specs actually differ between MSP430G variants here?

On this page the varying fields are: Package Type. Filter the table by the parameter you care about before picking an MPN.

Can I swap between 14-TSSOP (0.173", 4.40mm Width), 20-TSSOP (0.173", 4.40mm Width), 16-VQFN Exposed Pad, 32-VFQFN Exposed Pad packages in the same MSP430G family?

Only after footprint and thermal review. Packages listed here (14-TSSOP (0.173", 4.40mm Width), 20-TSSOP (0.173", 4.40mm Width), 16-VQFN Exposed Pad, 32-VFQFN Exposed Pad) use different land patterns and often different thermal resistance. Layout swaps need a new paste stencil at minimum, not just a BOM edit.

What is the lifecycle status of MSP430G variants?

Lifecycle values in our listing: Active. Status is per MPN suffix — one variant can be Active while another is NRND. Check PCN for your exact suffix before multi-year commitments.

What should I send for an RFQ on MSP430G?

Full manufacturer MPN (not just MSP430G), quantity, needed date code, reel vs tube, and any compliance docs (CoC, RoHS, conflict minerals). If you only know the base prefix, include a photo of the existing label or reel.
