It packs 32 KB of on-chip Flash program memory and 1 KB of RAM — enough to run a segmented LCD user interface alongside a Modbus RTU or custom sensor protocol stack without external memory. The internal oscillator eliminates the external crystal in non-timing-critical applications, saving two pins and a board layer. ## LCD integration and peripheral set The integrated LCD driver is the headline peripheral on this MSP430x4xx part — it drives segmented glass displays directly, which is why you see this MCU in utility meters, thermostats, and pump controllers that need a local readout. The brown-out detect and watchdog timer close the loop on supply integrity and code runaway without external supervisor ICs. 48 general-purpose I/O lines, plus SPI and UART/USART connectivity, cover the typical sensor interface and display backplane needs. The 100-LQFP package (14x14 mm body, 0.5 mm pitch) demands a 4-layer PCB for reliable fan-out of all 48 I/O — a 2-layer board will struggle with the inner rows. ## Temperature grade and supply planning An outdoor gas meter sitting in direct sun or a rooftop HVAC controller sees 85°C case temperature — the MSP430F4371IPZR stays within its operating envelope without derating. Texas Instruments lists this part as Active in its lifecycle status.","metaTitle":"MSP430F4371IPZR 16-bit MCU, 32KB Flash, LCD, 8MHz, 100-LQFP","metaDescription":"Texas Instruments MSP430F4371IPZR 16-bit MCU, 8MHz, 32KB Flash, 1KB RAM, LCD driver, -40 to 85°C.
