For a design running from two AA cells, the MCU stays operational through the full discharge curve. The 10 general-purpose I/O pins and the serial interfaces (I²C, SPI) remain functional across the voltage range, so no external level shifting is needed for common 3.3 V or 1.8 V sensor buses. The brown-out detect and POR circuits keep the MCU from corrupting Flash during supply transients in noisy environments. The ROHS3 compliance is current for global markets. ## 14-TSSOP package — footprint for space-constrained PCBs Housed in a 14-pin TSSOP with 0.65 mm pitch, the 4.40 mm body width fits on compact two-layer boards.","metaTitle":"TI MSP430G2131IPW14R 16-bit MCU, 1KB Flash, 128B RAM","metaDescription":"Texas Instruments MSP430G2131IPW14R 16-bit MCU with 16MHz core, 1KB Flash, 128B RAM, 8-ch 10-bit ADC, I²C/SPI.
