description
The Texas Instruments MSP430 is an ultra-low power mixed-signal microcontroller family consisting of several
deviceswhichfeaturedifferentsetsofmodulestargetedtovariousapplications. Themicrocontrollerisdesigned
to be battery operated for an extended application lifetime. With 16-bit RISC architecture, 16-bit integrated
registers on the CPU, and a constant generator, the MSP430 achieves maximum code efficiency. The digitally-
controlled oscillator, together with the frequency-locked-loop (FLL), provides a wakeup from a low-power mode
to active mode in less than 6 s.
