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 contribute to maximum code
efficiency. The digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less
than 1
渭s.
The MSP430x22xx series is an ultralow-power mixed signal microcontroller with two built-in 16-bit timers, a
universal serial communication interface, 10-bit A/D converter with integrated reference and data transfer
controller (DTC), two general-purpose operational amplifiers in the MSP430x22x4 devices, and 32 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
ends are another area of application.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
