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. ## On-chip data converters and serial connectivity","metaTitle":"TI MSP430A139IPZR 16-bit MCU, 8MHz, 116KB Flash, 100-LQFP","metaDescription":"Texas Instruments MSP430A139IPZR 16-bit MCU, 8MHz core, 116KB Flash, 8KB RAM, 80 I/O, industrial temp -40 to 85°C, 100-LQFP.
