MSP430F449REV

Product Summary

The Texas Instruments MSP430F449REV is an ultralow-power microcontroller. The microcontroller is designed to be battery operated for use in extended-time applications. The MSP430F449REV achieves maximum code efficiency with its 16-bit RISC architecture, 16-bit CPU-integrated registers, and a constant generator. The digitally-controlled oscillator provides wake-up from low-power mode to active mode in less than 6 μs. The MSP430F449REV is microcontroller configuration with two built-in 16-bit timers, a fast 12-bit A/D converter, 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.
