The device operates from 1.8 V to 3.6 V and is specified over the -40°C to 85°C industrial temperature range. ## 4 KB Flash and 256-byte RAM — sizing the firmware budget The 4 KB Flash (organized as 4K x 8 plus 256 bytes) is the non-volatile store for application code and constant tables. 256 bytes of RAM is tight — enough for a few sensor readings, a small state machine, and a communication buffer. Designs that need larger data arrays or a real-time OS will outgrow this part; it fits best in dedicated single-function controllers like a thermostat, a PIR sensor node, or a simple keypad interface. Slope A/D conversion is available for ratiometric measurements without an external ADC.","metaTitle":"Texas Instruments MSP430F1121AIDGVR 16-bit MCU, 8 MHz, 4 KB Flash","metaDescription":"Texas Instruments MSP430F1121AIDGVR 16-bit RISC MCU, 8 MHz, 4 KB Flash, 256 x 8 RAM, 14 I/O, 1.8 V to 3.6 V, -40°C to 85°C, 20-TVSOP tape and reel.
