描述 Description

The Texas Instruments MSP430 family of ultralow-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 6μs. The MSP430FG42x0 is a microcontroller configuration with a 16-bit timer, a high-performance 16-bitsigma-delta A/D converter, 12-bit D/A converter, two configurable operational amplifiers, 32 I/O pins, and a liquid crystal display driver. Typical applications for this device include analog and digital sensor systems, digital motor control, remote controls, thermostats, digital timers, hand-held meters, etc.
