MSP430F123IDW

TEXAS INSTRUMENTS  MSP430F123IDW  微控制器, 16位, 混合信号, MSP430F1xx, 8 MHz, 8 KB, 256 Byte, 28 引脚, SOIC

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 6µs. The device configurations with 16-bit timer, 22 general-purpose I/O pins and a built-in communication capability using asynchronous UART and synchronous SPI protocols in addition to a versatile analog comparator. This device operates at a maximum frequency of 8MHz.
