What sets this part apart from general-purpose MSP430 variants is the integrated LCD driver and the slope A/D converter — peripherals that directly address the bill-of-materials in utility meters (water, gas, heat), flow computers, and handheld instruments. The LCD segment drive eliminates an external display controller chip, while the slope A/D provides a ratiometric conversion path for resistive sensors (thermistors, strain gauges) without a separate ADC. ## 48 I/O in a 64-LQFP — what the pin count buys you Housed in a 64-LQFP package (10x10 mm body), the MSP430FW428IPMR brings out 48 general-purpose I/O lines. ## Peripheral set for battery-powered metering Beyond the LCD driver and slope A/D, the peripheral set includes a brown-out detect/reset (BOR), power-on reset (POR), a PWM timer, and a watchdog timer (WDT). The BOR and POR are essential for reliable startup from a battery that may sag under load.","metaTitle":"TI MSP430FW428IPMR 16-bit MCU, 8 MHz, 48 KB Flash","metaDescription":"Texas Instruments MSP430FW428IPMR 16-bit MCU with 8 MHz core, 48 KB Flash, 2 KB RAM, integrated LCD driver and slope A/D.
