No boost converter or LDO needed in a coin-cell remote sensor — that saves board area and quiescent draw. The POR (power-on reset) and WDT peripherals keep the startup sequence reliable even as the battery voltage sags toward 1.8 V. The 20-TSSOP package in a 4.4 mm wide body keeps the PCB footprint small, and at 0.65 mm pitch it is still reworkable with a standard fine-tip iron. ## Active lifecycle — no LTB chase needed TI lists the MSP430F1121AIPWR as Active (current production).","metaTitle":"TI MSP430F1121AIPWR 16-bit MCU, 8 MHz, 4 KB Flash, 20-TSSOP","metaDescription":"Texas Instruments MSP430F1121AIPWR 16-bit MCU, 8 MHz, 4 KB Flash, 256 B RAM, 14 I/O, -40°C to 85°C, 20-TSSOP.
