Product details

The peripheral list includes a brown-out detect and reset, DMA, LCD driver, PWM, watchdog timer, and 90 general-purpose I/O.

Supply range and 3.3 V compatibility

Yes, it is fully compatible with 3.3 V logic — the Vcc/Vdd range covers it directly. The LCD driver can run off an internal charge pump, which simplifies the display bias supply for battery-powered handhelds or panel meters.

The 0.4 mm pitch demands a controlled solder-paste stencil and a decent reflow profile — nothing exotic, but worth noting for a rework bench. MSL level is not listed in the record, but LQFP packages typically ship at MSL 3; treat the reel with standard moisture precautions if the seal is broken.

For dual-sourcing or a second-source gate, TI's MSP430F6xx family includes pin-compatible density variants — check the base product number MSP430F67491 for the exact Flash and RAM configuration you need.

Frequently asked questions

Can MSP430F67491AIPEUR be used for battery-powered LCD applications?

Yes. The ultra-low-power MSP430 architecture keeps sleep-mode current low, though the exact quiescent figure depends on the LCD frame rate and segment count.

What is the closest pin-compatible alternative to MSP430F67491AIPEUR?

Within the MSP430F6xx family, devices sharing the same 128-LQFP package and base product number MSP430F67491 are pin-compatible across Flash and RAM density options. For a direct parametric match, compare the Flash size, RAM size, and sigma-delta ADC channel count against other MSP430F67491 variants. No single alternative is listed in the record, but TI's product selector tool can filter by these parameters.
