Description

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.

Typical applications of the MSP430 family include electronic gas, water, and electric meters and other sensor systems that capture analog signals, convert them to digital values, process, displays, or transmits data to a host system.
