description
The Texas Instruments MSP430 family of ultralow
power microcontrollers consist of several devices
featuring different sets of peripherals targeted for
various applications. The architecture, combined
with five low power modes is optimized to achieve
extended battery life in portable measurement
applications. The device features a powerful
16-bit RISC CPU, 16-bit registers, and constant
generators that attribute to maximum code
efficiency. The digitally controlled oscillator (DCO)
allows wake-up from low-power modes to active
mode in less than 6µs.
The MSP430x11x series is an ultra low-power mixed signal microcontroller with a built in 16-bit timer and
fourteen I/O pins.
Typical applications include sensor systems that capture analog signals, convert them to digital values, and then
process the data and display them or transmit them to a host system. Stand alone RF sensor front-end is another
area of application.
