The 8-channel 10-bit ADC brings analog inputs on-chip, and the integrated brown-out reset, power-on reset, PWM timer, and watchdog timer keep external support chips off the board. 8 MHz clock ceiling. ## Memory budget: 4 KB Flash, 256 B RAM 4 KB of Flash (4K x 8 plus 256 bytes of info memory) and 256 bytes of RAM. Firmware must be hand-optimised — no RTOS, no fat libraries. ## Package and field-service angle No fine-pitch QFN or BGA — a rework station with a standard iron and some flux can swap it on a bench or even in a parking lot if you're careful. The 14 I/O pins are accessible on the outer leads, and the wide pitch (1.27 mm) means less risk of bridging during a field repair. If you're stocking a field-repair kit, this is the kind of part that goes in the bag.","metaTitle":"MSP430F1122IDW Texas Instruments 16-bit MCU, 8 MHz","metaDescription":"Texas Instruments MSP430F1122IDW 16-bit MCU with 8 MHz core, 4 KB Flash, 256 B RAM, 8-ch 10-bit ADC, industrial temp -40°C to 85°C, 20-SOIC.
