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 low-
power 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.
