description
The Texas Instruments MSP430 family of ultralow-power microcontrollers consists 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 contribute to maximum code
efficiency. The digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less
than 6 μs.
The MSP430x11x1(A) series is an ultralow-power mixed signal microcontroller with a built-in 16-bit timer,
versatile analog comparator and fourteen I/O pins.
Typical applications include sensor systems that capture analog signals, convert them to digital values, and then
process the data for display or for transmission to a host system. Stand alone radio frequency (RF) sensor front
end is another area of application. The I/O port inputs provide single slope A/D conversion capability on resistive
sensors.
