It carries 4 KB of on-chip Flash program memory and 256 x 8 bytes of RAM — enough for small sensor-logging or control loops that do not need external memory. ## NRND lifecycle — sourcing through independent channels Texas Instruments lists the MSP430F1121IDWR as NRND (Not Recommended for New Designs). The part is no longer the first choice for a new BOM, but it remains available through independent distribution for existing production runs and sustainment programs. For a new design, a pin-compatible or functionally equivalent alternative within the MSP430 family should be evaluated. ## Industrial temperature grade and 20-SOIC package The tape-and-reel packaging supports automated pick-and-place assembly.","metaTitle":"MSP430F1121IDWR Texas Instruments MCU, 16-bit, 8 MHz","metaDescription":"Texas Instruments MSP430F1121IDWR 16-bit MCU, 8 MHz, 4 KB Flash, 256 B RAM, 14 I/O, 20-SOIC.
