Product details

You can qualify this into a new production run without planning an end-of-life migration.

Three 16-bit sigma-delta ADCs — the metering-specific differentiator

Those ADCs are the reason this part exists — they are designed for single-phase energy metering, letting the MCU sample voltage and current channels directly without an external analog front-end. The 8.4 MHz core clock is enough to run the metrology algorithm and handle SPI or UART communication to a host processor or display driver. Program memory is 16 KB of Flash with 512 bytes of RAM — a tight but workable footprint for a dedicated metering application where the firmware is fixed at the factory.

Supply rails and temperature grade — industrial metering enclosure fit

Packaged in a 64-LQFP (10x10 mm body), the MSP430FE425IPM is a surface-mount device that reflows with standard lead-free profiles. The tray shipping medium is common for production-volume programming houses that handle the Flash before board assembly.

Frequently asked questions

What is the difference between MSP430FE425IPM and MSP430FE427IPM?

The MSP430FE427IPM is a higher-density sibling in the same metering family — it doubles the program Flash to 32 KB and the RAM to 1 KB while keeping the same 64-LQFP footprint, three 16-bit sigma-delta ADCs, and peripheral set. The MSP430FE425IPM's 16 KB Flash is the cost-optimized choice for firmware that fits the smaller memory budget.

Can the MSP430FE425IPM be used for energy metering?

Yes, the three 16-bit sigma-delta ADCs are specifically designed for single-phase energy metering. The MSP430FE425IPM samples voltage and current channels directly and runs the metrology algorithm on the 8.4 MHz CPU16 core, with SPI or UART for data output.

What programming tools are compatible with the MSP430FE425IPM?

The MSP430FE425IPM uses the standard TI MSP430 JTAG/SBW (Spy-Bi-Wire) interface. Any MSP430-compatible programmer or debugger — such as the MSP-FET or eZ430 — works with this device. The internal oscillator means no external clock is needed for programming.
