The Texas Instruments MSP430 family of ultralow-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 inportable measurement applications. The device features a powerful 16-bit RISC CPU, 16-bit registers, andconstant 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 1µs.
The MSP430G2x01/11 series is an ultralow-power mixed signal microcontroller with a built-in 16-bit timer and ten I/O pins. The MSP430G2x11 family members have a versatile analog comparator. For configuration details seeTable1. Typical applications include low-cost sensor systems thatcapture analog signals, convert them to digital values, and then process the data for display or for transmission to a host system.
