说明

The Texas Instruments MSP430 is an ultralow-power mixed signal microcontroller family consisting of several devices featuring different sets of modules targeted to various applications. The controller is designed to be battery-operated for an extended application lifetime. With the 16-bit RISC architecture, 16 integrated registers on the CPU, and a constant generator, the MSP430 achieves maximum code efficiency. The digital-controlled oscillator, together with the frequency lock loop (FLL), provides a wake-up from a low-power mode to an active mode in less than 6 us. The MSP430x33x series microcontrollers have built-in hardware multiplication and communication capability using asynchronous (UART) and synchronous protocols.
