16-bit MSP430 with integrated LCD drive and slope A/D
The Texas Instruments MSP430A023IPM is a 16-bit MSP430 microcontroller from the MSP430x4xx series, built around the MSP430 core. It packs 8KB of FLASH program memory and 256 x 8 bytes of RAM, runs at 8 MHz from an internal oscillator, and provides 48 general-purpose I/O lines. On-chip peripherals include a slope A/D converter, an LCD driver, brown-out detection, POR, PWM, and a watchdog timer. It operates from 1.8 V to 3.6 V supply over the industrial temperature range of -40°C to 85°C, making it suitable for outdoor telecom, factory automation, and automotive cabin applications. The part is supplied in a 64-LQFP package (10x10 mm) on tray.
Integrated LCD driver and slope A/D — what they save on the BOM
The on-chip LCD driver can directly drive a segment LCD panel without an external controller, saving a chip and board area. The slope A/D converter provides a low-resolution analog input path — adequate for temperature sensing, potentiometer feedback, or battery monitoring — without adding an external ADC. For higher-resolution or faster conversions, you would need an external SAR or sigma-delta ADC.
