Industrial temperature range and peripheral set
The peripheral list includes a brown-out detect and reset, DMA, LCD driver, PWM, watchdog timer, and 90 general-purpose I/O. Connectivity covers I²C, IrDA, LINbus, SPI, and UART/USART — enough to talk to an external radio, a shunt-based current sensor, or a host processor over a serial link.
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.
Package and mounting
Housed in a 128-LQFP (20x14 mm body), this is a surface-mount part intended for reflow assembly. 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.
Lifecycle and sourcing
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.
