The Texas Instruments MSP430P325IFN is a 16-bit MSP430x3xx microcontroller with an 8 MHz core, 16 KB of one-time-programmable (OTP) program memory, 512 bytes of RAM, and an integrated segment LCD driver. It packs 14 general-purpose I/O, a UART/USART serial interface, a 6-channel 14-bit ADC, and an internal oscillator into a 68-lead PLCC package (24.23 mm square).
Where it fits — and where it doesn't
The integrated LCD driver is the headline feature — it drives a segment LCD glass panel directly, eliminating an external display controller and saving board area. The 8 MHz core and 512-byte RAM limit it to control-loop and UI-logging tasks — think gas-pump display, thermostat front-end, or portable instrument readout. It is not suited for real-time motor control or data-heavy processing.
The 16 KB program memory is OTP — one-time programmable. Once the device is programmed, the code is permanent. There is no erase cycle, no reprogramming, no firmware update path.
Texas Instruments has marked the MSP430P325IFN as obsolete. No further factory orders are accepted; no last-time-buy window remains open. We source and quote each request individually against an RFQ, confirming availability and current pricing at quote time. No standard lead time applies; the lot condition and date-code spread vary per procurement.
The 8 MHz core speed handles LCD-update and key-scan loops. The 512-byte RAM limits display buffer and stack depth.
