DESCRIPTION
The Texas Instruments MSP430 family of ultra-low-power microcontrollers consists 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 contribute to maximum code efficiency.
The digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 6 µs.
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, hand-held meters, etc.
