The Texas Instruments MSP430G2213IPW28R is a 16-bit ultra-low-power microcontroller from the MSP430G2xx series. It runs at 16 MHz with 2 KB of Flash program memory and 256 bytes of RAM, making it suited for single-function sensor handlers, simple control loops, or battery-powered data loggers where code fits in a constrained footprint. The 24 I/O pins and integrated peripherals — brown-out detect, POR, PWM, watchdog timer, and a DMA controller — let it handle basic mixed-signal tasks without external glue logic.
The DMA controller allows peripheral-to-memory transfers without CPU intervention, useful for logging sensor data while the core sleeps.
