Product details

The 80-LQFP package with 48 I/O gives enough headroom for a keypad, display segment lines, and a few external peripherals before needing a larger part.

Industrial temperature rating — what it buys you

The brown-out detect and reset circuit keeps the core from corrupting Flash during a cold-crank or brown-out event, which matters when the board lives on a 24 V industrial rail with long cable runs.

Active lifecycle — no end-of-life clock ticking

That means no last-time-buy window to schedule, no risk of a forced redesign mid-production.

Package and supply — what the layout engineer sees

The 80-LQFP package (12x12 mm body) is a hand-solderable fine-pitch QFP with a 0.5 mm lead pitch — no BGA rework required, which simplifies prototype assembly and field repair. The 48 I/O include the LCD segment and common outputs, plus the ADC and DAC analog pins; the datasheet's pin assignment should be checked against the LCD glass layout early in the schematic phase to avoid a board spin.

Frequently asked questions

What is the difference between MSP430F477IPNR and MSP430F477IPM?

The MSP430F477IPNR and MSP430F477IPM share the same core, memory, and peripheral set — the difference is the package. The IPNR variant is an 80-LQFP, while the IPM variant is a 64-pin LQFP. The 80-pin package gives 48 I/O versus fewer on the 64-pin version, which matters when the design needs more LCD segment lines or parallel bus signals.
