Product details

16-bit MSP430 MCU with integrated LCD drive and 8 MHz core

The Texas Instruments MSP430A139IPZR is a 16-bit MSP430 microcontroller from the MSP430x4xx series, clocked at 8 MHz and built around the ultra-low-power MSP430 core. It carries 116 KB of Flash program memory and 8 KB of RAM, with 80 general-purpose I/O lines and a rich set of on-chip peripherals including a 12-bit ADC, dual 12-bit DACs, and a direct LCD driver — making it a fit for metering, portable instrumentation, and human-machine interface panels that need a single-chip controller with a segmented display. The 8 MHz core speed is the throughput ceiling for this device.
