MC68681FN UART interface — serial communications IC

The MC68681FN is a UART peripheral IC from Motorola designed for serial communications and legacy interface support. The MC68681FN provides buffered serial I/O with configurable settings to match common baud rates and protocols. It integrates cleanly with microprocessors and helps offload serial handling to dedicated hardware, improving CPU efficiency. Designers use this device in terminals, embedded controllers, and communications equipment where robust serial timing and buffering are required. The PL package supports reliable mounting and long-term operation. If you need a proven UART solution, order the MC68681FN from Florida Circuit to confirm stock and lead times.
