TEXAS INSTRUMENTS MSP430F5438AIZQWT 微控制器, 16位, 混合信号, MSP430F5xx, 25 MHz, 256 KB, 16 KB, 113 引脚, BGA
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 3.5µs typical. The device configurations with three 16-bit timer, 12-bit A/D converter, three-channel internal DMA, up to four universal serial communication interfaces USCIs, a 32-bit hardware multiplier and 87 general-purpose I/O pins. This device operates at a maximum frequency of 25MHz.
