Overview
The Texas Instruments MSP430F2274IDAR is an ultra-low-power mixed signal microcontroller from the MSP430 family. This device is designed to optimize power consumption, making it ideal for applications requiring extended battery life. It features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency. The microcontroller includes a digitally controlled oscillator (DCO) that allows for ultrafast wake-up from low-power modes to active mode in less than 1 μs.
The MSP430F2274IDAR is part of the MSP430F22x4 series, which includes two built-in 16-bit timers, a universal serial communication interface, a 10-bit A/D converter with integrated reference and data transfer controller (DTC), and two general-purpose operational amplifiers. It also has 32 general-purpose I/O pins.
