DESCRIPTION

The Texas Instruments MSP430™ family of ultra-low-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 contribute to maximum code efficiency.

The digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 1 μs.

The MSP430F22x4/MSP430F22x2 series is an ultra-low-power mixed signal microcontroller with two built-in 16-

bit timers, a universal serial communication interface, 10-bit A/D converter with integrated reference and data

transfer controller (DTC), two general-purpose operational amplifiers in the MSP430F22x4 devices, and 32 I/O

pins.

Typical applications include sensor systems that capture analog signals, convert them to digital values, and then

process the data for display or for transmission to a host system. Stand-alone radio-frequency (RF) sensor front

ends are another area of application.
