With 31 I/O lines in a 40-pin QFN, most of the package pins are usable for GPIO or alternate functions. That means it's safe to specify into a new BOM or replenish an existing line without worrying about a forced redesign.","metaTitle":"TI MSP430F5131IRSBR 16-bit MCU, 25 MHz, 8 KB Flash, 40-WQFN","metaDescription":"Texas Instruments MSP430F5131IRSBR 16-bit MCU with 25 MHz CPUXV2 core, 8 KB Flash, 1 KB RAM, industrial temp -40°C to 85°C, 40-WQFN package.
