The LCD driver on the peripheral list can drive a segment display directly, saving an external driver IC. The lifecycle stage for this part is recorded as eol_hot, which indicates end-of-life planning is active. The official product status is marked Active, so production has not ceased, but procurement should treat this as a part with a finite window. For dual-sourcing or a drop-in replacement, the MSP430F67621 family shares the same pinout across density options — verify the specific Flash/RAM and ADC count against your firmware image.","metaTitle":"Texas Instruments MSP430F67621IPNR 16-bit MCU, 25 MHz, 64 KB Flash","metaDescription":"MSP430F67621IPNR 16-bit MCU with 25 MHz CPU, 64 KB Flash, 4 KB RAM, three 24-bit sigma-delta ADCs.
