Product details

16 MHz MSP430 core with 1 KB Flash — what fits in that memory budget

The MSP430G2132IPW20 has 1 KB of Flash and 128 bytes of RAM. That memory fits a single control loop, a few sensor readings, and a simple communication protocol — think a temperature monitor reporting over I²C, a basic PWM fan controller, or a battery-voltage supervisor. Connectivity runs through I²C, SPI, and the Universal Serial Interface (USI).

The base product number is MSP430G2132, so any PCN or documentation updates track under that root.

Package and footprint — 20-TSSOP

It is a surface-mount part.

Frequently asked questions

What are alternatives to MSP430G2132IPW20 in the same family?

Within the MSP430G2xx series, pin-compatible alternatives with more memory include the MSP430G2232 (2 KB Flash) and MSP430G2332 (4 KB Flash), both in the same 20-TSSOP footprint. The trade-off is program memory size versus cost — the G2132 is the entry point at 1 KB.

Is MSP430G2132IPW20 compatible with 3.3 V logic?

Yes. The supply range goes up to 3.6 V, so the device operates directly on a 3.3 V rail. All I/O pins are 3.3 V tolerant within that supply range.
