No AEC-Q100 qualification is listed, so skip it for any vehicle powertrain or chassis-domain application. ## Lifecycle and sourcing — what to expect The MSP430F123IDWR carries an EOL-hot lifecycle marker, meaning TI has announced end-of-life for this device. Production is still active per the listing, but the window for last-time buys is narrowing.","metaTitle":"TI MSP430F123IDWR 16-bit MCU, 8MHz, 8KB Flash, 28-SOIC","metaDescription":"Texas Instruments MSP430F123IDWR 16-bit MCU with 8MHz core, 8KB Flash, 256B RAM, 22 I/O, SPI/UART, industrial temp -40°C to 85°C.
