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. The integrated LCD driver eliminates the need for an external display controller.
Industrial temperature range and package
Rated for -40°C to 85°C, this MCU is specified for industrial environments. The 100-LQFP package (14x14 mm body) is a standard footprint for mid-density MCUs.
On-chip data converters and serial connectivity
The MSP430A139IPZR includes a 12-channel, 12-bit ADC and two 12-bit DACs, sufficient for analog sensor conditioning and closed-loop control in a single-chip architecture. Serial interfaces cover I²C, SPI, UART/USART, IrDA, LINbus, and SCI — enough protocol support to talk to most industrial sensors, external EEPROMs, and host controllers without glue logic.
