TI MSP430G2252TDA1

The MSP430 family of ultra-low-power microcontrollers consists of several devices featuring different peripheral sets tailored to various applications. This architecture, combined with 5 low-power modes, is optimized to extend battery life in portable measurement applications. The device features a powerful 16-bit RISC CPU, 16-bit registers, and a constant generator that aids in achieving maximum code efficiency.

The MSP430G2252 is an ultra-low-power mixed-signal microcontroller. The processor features a built-in 16-bit timer, up to 16 touch-enabled I/O pins, built-in communication capability using a universal serial communication interface, and a versatile analog comparator. The MSP430G2252 includes a 10-bit analog-to-digital (A/D) converter. Typical applications include low-cost sensor systems that capture analog signals, convert them to digital values, and then process the data for display or transmission to a host system.
