The MSP430F439IPN carries an end-of-life hot status, meaning the manufacturer has announced discontinuation and the last-time-buy window is closing or closed. For new BOMs or long-life products, evaluate a pin-compatible MSP430x4xx variant as a drop-in replacement.","metaTitle":"TI MSP430F439IPN 16-bit MCU, 60KB Flash, 8MHz, 80-LQFP","metaDescription":"Texas Instruments MSP430F439IPN 16-bit MCU with 60KB Flash, 8MHz core, integrated LCD driver, 12-bit ADC, industrial temp -40°C to 85°C.
