The 14 I/O lines and 8-channel 10-bit ADC cover most low-pin-count analog sensing tasks without external muxing. ## Active lifecycle — no near-term obsolescence For MRO stock and production BOMs, this means the supply channel remains open through normal distribution.","metaTitle":"Texas Instruments MSP430F1122IDWR 16-bit MCU, 8 MHz","metaDescription":"Texas Instruments MSP430F1122IDWR 16-bit MCU, 8 MHz core, 4 KB Flash, 256 B RAM, 14 I/O, 8x10-bit ADC, -40 to 85°C, 20-SOIC.
