For low-power applications, the clock can be divided down or the device placed in sleep modes between processing events. ## 2 KB Flash and 128 B RAM — firmware fit check Program memory is 2 KB (organized as 2K x 8 plus 256 bytes for info storage). That is a tight fit for compiled C code with a small real-time kernel; hand-tuned assembly or a minimal state machine fits comfortably. The 128-byte RAM is the hard limit for stack depth and global variables — watch for stack overflow in interrupt-heavy designs. The Flash is in-system programmable via the JTAG/SBW interface, so field updates are possible if the bootloader fits. End-of-life (hot) lifecycle status. Manufacturer has issued a last-time-buy notice; production is winding down. For existing BOM lines, we source this part through independent distribution channels.","metaTitle":"TI MSP430F1111AIDWR 16-bit MCU, 8 MHz, 2 KB Flash, 20-SOIC","metaDescription":"Texas Instruments MSP430F1111AIDWR 16-bit MCU, 8 MHz core, 2 KB Flash, 128 B RAM, industrial temp -40°C to 85°C, 20-SOIC.
