MSP430F449IPZ

Product Summary

The MSP430F449IPZ is an ultralow-power microcontroller consisting of several devices featuring different sets of modules targeted to various applications. The microcontroller is designed to be battery operated for use in extended-time applications. The MSP430 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 us. The MSP430F449IPZ is a microcontroller configurations 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. Typical applications of the MSP430F449IPZ 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 displays it on a LCD pane.
