The Texas Instruments MSP430 series is an ultra low-power microcontroller family consisting of several devices featuring different sets of modules targeted to various applications. The microcontroller is designed to be battery operated for an extended application lifetime. With 16-bit RISC architecture, 16 bit integrated registers on the CPU, and the constant generator, the MSP430 achieves maximum code efficiency. The digitallycontrolled oscillator provides fast wake-up from all low-power modes to active mode in less than 6 ms.
