Product details

4 KB Flash and 256 B RAM — sizing the firmware footprint

With 4 KB of Flash and 256 bytes of RAM, this part is sized for small supervisory tasks: reading a few sensors, driving a simple PWM output, or managing a serial protocol bridge. The 256-byte RAM ceiling means no dynamic allocation — firmware must be statically budgeted. The 10-bit ADC with eight channels covers multi-sensor analog front ends without an external converter.

Through-hole 20-DIP — rework-friendly footprint

The 20-pin DIP (0.300" body width) through-hole package is a deliberate choice for prototyping, educational kits, and low-volume production where hand-soldering or socketing is preferred. It is not a space-optimized option — the 7.62 mm row spacing and through-hole leads take up more board area than an equivalent TSSOP — but it simplifies rework and inspection.

It carries ROHS3 compliance.

Frequently asked questions

Is MSP430G2332IN20 RoHS compliant?

Yes, it is ROHS3 compliant per the TI listing.

How does MSP430G2332IN20 compare to MSP430G2553IN20?

The MSP430G2553 is a higher-density sibling in the same G2xx family — it typically offers more Flash and RAM (16 KB / 512 B vs. 4 KB / 256 B) and a 16 MHz core, but the G2332 is the cost-optimized entry point for smaller firmware loads. Both share the same 20-pin DIP footprint and peripheral set, so a board designed for the G2332 can accept the G2553 as a drop-in upgrade if the firmware fits.

What is the difference between MSP430G2332IN20 and MSP430G2452IN20?

The MSP430G2452 is another G2xx variant with the same 16 MHz core and 8 KB Flash, but it lacks the full 8-channel 10-bit ADC — it carries a comparator instead. The G2332 includes the 8-channel 10-bit ADC, making it the better fit for designs that need analog-to-digital conversion without an external ADC chip.
