SCC68692C1N40,602

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SCC68692C1N40,602 is a Dual Universal Asynchronous Receiver/Transmitter (DUART) manufactured by NXP Semiconductors. It provides two full-duplex asynchronous receiver/transmitter channels in a single package. The device operates on a single +5 V power supply and supports data transfer rates up to 1 MB/sec at 1X clock or 125 kB/sec at 16X clock. It features quadruple buffered receiver data registers, programmable baud rate generators, and a 16-bit counter/timer. The component is housed in a 40-pin Plastic Dual In-Line Package (DIP).

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation to confirm temperature range and package type. Confirm availability status as commercial versions may have different lifecycle stages than industrial variants. Ensure compatibility with existing S68000 bus architectures before integration into new designs.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual independent UART channels are required within a single footprint. Consider the PLCC-44 variant if surface mount technology is preferred over through-hole DIP packaging. Verify that the required baud rates align with the available fixed rates or external clock inputs provided by the internal generator.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the SCC68692 family of dual asynchronous receiver/transmitters. It is functionally compatible with the SCN68681 device. The series supports both commercial and industrial temperature ranges, offering flexibility for various environmental operating conditions while maintaining standard TTL logic levels.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

SCC68692E1N40 serves as the industrial temperature range equivalent. SCN68681 is a compatible single-channel alternative. Verify pinout compatibility when substituting with other DUART devices from different manufacturers.
