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 internal oscillators allow wake-up from low-power modes to active mode in less than 5 μs.

The MSP430C09x and MSP430L092 series are microcontroller configurations with two 16-bit timers, an

ultra-low-voltage 8-bit analog-to-digital (A/D) converter, an 8-bit digital-to-analog (D/A) converter, and up to 11 I/O

pins.

Typical applications for this device include single-cell systems requiring a full analog signal chain.
