XR68C681CJ-F

Overview

The XR68C681CJ-F is a dual-channel CMOS serial I/O controller manufactured by MaxLinear, Inc. It operates at a maximum data rate of 0.125 Mbps and supports a nominal supply voltage of 5 V. The device is housed in a 44-pin Plastic Leaded Chip Carrier (PLCC) package with dimensions of 16.59 x 16.59 mm. It features an internal oscillator and timer/counter capabilities. The component is RoHS3 compliant and classified under EAR99 export controls.

Feature Summary

Dual UART channel architecture for simultaneous serial communication
CMOS technology ensuring low power consumption
Integrated internal oscillator eliminating external clock requirements
Built-in timer/counter functionality for precise baud rate generation

Applications

Industrial control systems requiring reliable serial data transmission
Embedded computer interfaces for legacy protocol support
Communication equipment utilizing MC68681 bus compatibility

Procurement Notes

Verify the specific suffix 'F' against the manufacturer's latest documentation to confirm compliance status and material composition. Check for any Product Change Notices (PCN) related to assembly site changes or material substitutions. Confirm that the 44-PLCC package availability aligns with current manufacturing schedules, as discontinuation notices may affect long-term supply stability.

Selection Notes

Select this component when a dual-channel UART interface with MC68681 bus compatibility is required. Ensure the design accommodates the 44-PLCC surface mount footprint. Verify that the 5V supply voltage matches the system power rails. Consider the 0.125 Mbps speed limit for application timing requirements before finalizing the selection.

Part Context

This part belongs to the XR68C series of serial I/O controllers from MaxLinear. It is functionally compatible with the Motorola MC68681 standard. The device serves as a bridge between parallel microprocessor buses and serial communication lines, supporting standard asynchronous protocols.
