XR82C684CJTR-F

Overview

The XR82C684CJTR-F is a quad-channel UART interface integrated circuit manufactured by MaxLinear. It operates within a supply voltage range of 3.0 V to 5.5 V and supports data rates up to 1 Mbps. The device features an internal oscillator and timer/counter capabilities, housed in a 44-pin PLCC package with J-leads. Designed for surface-mount installation, it functions across commercial temperature ranges from 0°C to +70°C. This component provides serial communication interfaces compatible with standard asynchronous protocols.

Feature Summary

Quad-channel architecture supporting four independent UART ports
Internal oscillator and timer/counter functionality
Motorola bus compatibility for system integration

Applications

Industrial control systems requiring multiple serial connections
Embedded devices needing asynchronous communication interfaces
Data acquisition systems utilizing serial I/O controllers

Procurement Notes

This component is officially discontinued and no longer in production. Verification of availability requires checking secondary market distributors or surplus inventory providers. Buyers must confirm the specific revision level and physical condition of available units, as original manufacturer support is terminated. Compliance documentation should be reviewed prior to procurement.

Selection Notes

Engineers replacing this part should evaluate current alternatives based on channel count and pin compatibility. The discontinuation status necessitates reviewing long-term supply chain stability for new designs. Compatibility with existing Motorola bus interfaces and voltage requirements must be validated against potential substitute components to ensure seamless integration without redesign.

Part Context

The XR82C684 series belongs to MaxLinear's portfolio of UART interface ICs, previously associated with Exar Corporation branding. These devices are designed for applications requiring reliable serial communication in embedded environments. The specific CJTR suffix indicates a tape-and-reel packaging format suitable for automated assembly processes.

Replacement Considerations

Publicly confirmed substitutes include the XR82C684CJ-F (tube package) and other variants within the XR82C684 family. Engineers should verify pinout compatibility and electrical specifications when selecting alternative packages or updated revisions from the same product line.
