Product details

16 KB Flash, 512 B RAM, on-chip LCD driver — the metering-tailored MSP430

It runs at 8 MHz and integrates 16 KB of program Flash with 512 bytes of RAM — enough for a dedicated metrology firmware stack that polls a sensor and drives a segmented LCD. The on-chip LCD controller and slope A/D converter eliminate the need for separate display driver and ADC ICs, shrinking the BOM for gas, water, and heat meters.

48 I/O, internal oscillator, brown-out detect — peripheral set for a self-contained node

The slope A/D provides a low-cost way to read resistive or capacitive sensors common in flow measurement.

TI lists the MSP430FW425IPMR as Active.

Frequently asked questions

Is MSP430FW425IPMR obsolete?

No. It is qualified for new designs and available through the independent distribution channel.

Does MSP430FW425IPMR have an LCD driver?

Yes. The peripheral set includes an integrated LCD controller, which drives a segmented display directly without an external driver IC. This is a key feature for utility meter applications where a local readout is required.

What is the closest pin-compatible alternative to MSP430FW425IPMR?

Within the MSP430FW4xx family, devices with the same 64-LQFP footprint and similar peripheral mix (LCD, slope A/D) are pin-compatible across density options. The MSP430FW427 or MSP430FW428 offer more Flash and RAM while maintaining the same package and pinout, allowing a drop-in upgrade without a board respin.
