MSP430F4X microcontrollemsp430r

　　The Texas Instruments MSP430 family of ultralow 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 devices feature 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 6 µs.

　　The MSP430x43x（1） and the MSP430x44x（1） series are microcontroller configurations with two built-in 16-bit timers， a fast 12-bit A/D converter （not implemented on the MSP430F43x1 and MSP430F44x1 devices）， one or two universal serial synchronous/asynchronous communication interfaces （USART）， 48 I/O pins， and a liquid crystal driver （LCD） with up to 160 segments. Typical applications include sensor systems that capture analog signals， convert them to digital values， and process and transmit the data to a host system， or process this data and display it on a LCD panel. The timers make the configurations ideal for industrial control applications such as ripple counters， digital motor control， EE-meters， hand-held meters， etc. The hardware multiplier enhances the performance and offers a broad code and hardware-compatible family solution.
