3 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 the device to wake up from low-power modes to active mode in

less than 1 μs.

The MSP430G2x53 series are ultra-low-power mixed signal microcontrollers with built-in 16-bit timers, up to

24 I/O capacitive-touch enabled pins, a versatile

analog comparator, a 10-bit analog-to-digital (A/D)

converter, and built-in communication capability using

the universal serial communication interface. For configuration details, see Table 1.

Typical applications include low-cost 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.
