The 24 I/O are all 5 V tolerant on this family, which simplifies level translation when interfacing to legacy 5 V logic or sensors.","metaTitle":"Texas Instruments MSP430G2403IRHB32R 16-bit MCU, 16 MHz","metaDescription":"Texas Instruments MSP430G2403IRHB32R 16-bit MCU, 16 MHz core, 8 KB Flash, 512 B RAM, 24 I/O, -40 to 85°C, 32-VQFN.
