MSP430F249TPM

TEXAS INSTRUMENTS  MSP430F249TPM  微控制器, 16位, 混合信号, MSP430F2xx, 16 MHz, 60 KB, 2 KB, 64 引脚, LQFP

The is a 16-bit ultra-low-power Mixed-signal Microcontroller features a powerful 16-bit RISC MSP430 CPU, 16-bit registers and constant generators that contribute to maximum code efficiency. The architecture combined with five low-power modes, is optimized to achieve extended battery life. The digitally controlled oscillator DCO allows wake-up from low-power modes to active mode in less than 1µs. The device configurations with two 16-bit timers, 12-bit A/D converter, a comparator, a hardware multiplier, four universal serial communication interface USCI modules and 48 general-purpose I/O pins. This device operates at a maximum frequency of 16MHz.
