The NXP Semiconductors 68681 is a MOS technology serial I/O controller, part of the 68681 series. This component offers two asynchronous serial channels, each capable of data transfer rates up to 0.125 Mbps. It supports various communication standards including ASYNC, BIT, and BISYNC, with data encoding/decoding methods such as NRZ, NRZI, BIPH-MARK (FM1), BIPH-SPACE (FM0), and BIPH-LEVEL (Manchester). The controller features an 8-bit external data bus and is compatible with the 6800 bus architecture. Operating within a temperature range of -55°C to 125°C, it requires a supply voltage of 5.0V nominal (4.75V to 5.25V). The device is housed in a 44-terminal CQCC package (JESD-30 Code: S-CQCC-N44) with a terminal pitch of 1.270 mm. Applications for this component are found in industrial automation and data acquisition systems.
