MSP430F1491IRTDT

混合信号微控制器 MIXED SIGNAL MICROCONTROLLER

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 two 16-bit timers, a comparator, a hardware multiplier and 48 general-purpose I/O pins. This device operates at a maximum frequency of 8MHz.
