description
The Texas Instruments MSP430 series is a ultra low-power 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 the constant generator, the MSP430 achieves maximum code efficiency. The digital-controlled
oscillator, together with the frequency lock loop (FLL), provides a fast 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.
PRODUCTION DATA information is current as of publication date.
