1.3 Description

The TI 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 lowpower

modes to active mode in less than 6 μs.

The MSP430xG461x series are microcontroller configurations with two 16-bit timers, a high-performance

12-bit ADC, dual 12-bit DACs, three configurable operational amplifiers, one universal serial

communication interface (USCI), one universal synchronous/asynchronous communication interface

(USART), DMA, 80 I/O pins, and a segment liquid crystal display (LCD) driver with regulated charge

pump.
