description
The Texas Instruments MSP430 family of ultralow power microcontrollers consist of several devices featuring
different sets of peripherals targeted for various applications. The architecture, combined with five low power
modes is optimized to achieve extended battery life in portable measurement applications. The device features
a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that attribute to maximum code efficiency.
The digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 6µs.
The MSP430xW42x series are microcontroller configurations with two built-in 16-bit timers, a comparator, 96
LCD segment drive capability, a scan interface, and 48 I/O pins.
Typical applications include sensor systems that capture analog signals, convert them to digital values, and
process the data and transmit them to a host system. The comparator and timers make the configurations ideal
for gas, heat, and water meters, industrial meters, counter applications, handheld meters, etc.
