MSP430F249MPMEP Ultra-Low Power MCU

Texas Instruments' MSP430F249 microcontroller has two built-in 16-bit timers, a fast 12-bit analog-to-digital converter (except the MSP430F24x1), a comparator, four universal serial communication interface (USCI) modules (two in the MSP430F23x) and as many as 48 I/O pins. The device features a powerful 16-bit RISC CPU, 16-bit registers and constant generators that contribute to maximum code efficiency. The calibrated digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 1 µs.
