description
The Texas Instruments MSP430 is an ultra-low power mixed signal microcontroller family consisting of several
devices which features 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 s. The MSP430x33x series micro-controllers 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, converts them to digital values, processes, displays, or transmits them to
a host system.
