Mixed-signal MCU with LCD drive — what it brings to the BOM
The MSP430FG4250IRGZT: Its standout feature is the integrated LCD controller, which drives a display segment directly without a separate driver chip — a real board-space and cost saver for metering, instrumentation, and portable panel designs. On the analog side it packs a 5-channel 16-bit ADC and a single 12-bit DAC, so you can handle sensor conditioning and analog output generation on one die.
NRND — plan the transition now
That means TI is not actively promoting it for fresh BOMs, and the long-term supply window is finite. For a production line that already qualifies this part, you want to secure last-time-buy inventory or evaluate a pin-compatible successor in the MSP430 family before the EOL notice arrives. We source this through independent distribution and can quote current availability against an RFQ — but the clock is ticking on new-design starts.
