Overview
The XR88C681CP/40 is a dual-channel CMOS Universal Asynchronous Receiver and Transmitter (UART) manufactured by MaxLinear, Inc. It features two independent full-duplex serial communication channels compatible with the MC68681 architecture. The device operates at data rates up to 1 Mbps and supports a supply voltage of 5V. It is housed in a 40-pin Dual In-line Package (DIP) with a standard pinout. Key internal components include an integrated oscillator, timer/counters, and control logic for serial data transmission and reception.
Feature Summary
- Dual independent full-duplex serial communication channels
- CMOS technology for low power consumption
- Integrated oscillator and timer/counters
- MC68681 compatible pinout and functionality
Applications
- Industrial serial communication systems
- Embedded controller interfaces
- Legacy computer peripheral connections
Procurement Notes
Verify component authenticity through authorized distributors or manufacturer channels. Confirm package integrity upon receipt. Check for moisture sensitivity indicators if storage conditions are uncertain. Ensure compatibility with existing PCB footprints before integration. Review datasheet revisions for any functional updates.
Selection Notes
Select this component when MC68681 compatibility is required in a DIP package. Consider thermal dissipation requirements for enclosed environments. Verify signal levels match system logic standards. Evaluate pin count constraints against alternative packages like PLCC if space is limited.
Part Context
This part belongs to the XR88C681 series of dual UARTs. It shares core functionality with variants such as the XR88C681CJ and XR68C681CJTR-F, differing primarily in packaging and temperature range specifications. The CP suffix denotes the plastic DIP package format.
Replacement Considerations
Direct substitutes include XR88C681CJ and XR68C681CJTR-F. Verify package dimensions and pin compatibility before replacement. Cross-reference electrical specifications to ensure operational equivalence.
