XR82C684CJTR/44-F

Overview

The XR82C684CJTR/44-F is a quad universal asynchronous receiver and transmitter manufactured by MaxLinear. It features four independent full-duplex communication channels with 3-byte transmit and receive FIFOs per channel. The device operates at data rates up to 1 Mb/s within a supply voltage range of 4.75 V to 5.25 V, consuming 15 mA of operating current. It supports Intel and Motorola bus interfaces and functions within an ambient temperature range of 0°C to +70°C. The component is housed in a PLCC-44 surface-mount package.

Feature Summary

Integrates four fully independent UART channels for simultaneous asynchronous communication
Includes small 3-byte FIFO buffers on both transmit and receive paths for each channel
Supports standard Intel and Motorola bus interface protocols

Applications

Industrial control systems requiring multiple serial ports
Embedded computer architectures utilizing legacy UART interfaces
Communication modules needing compact multi-channel serial connectivity

Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Distribution availability is restricted or unavailable through major authorized distributors such as Mouser. Verification of authenticity and condition is critical when sourcing from secondary markets due to discontinuation status.

Selection Notes

Designers should evaluate alternative components from the same family or newer generations due to the EOL status. Considerations include pin compatibility, FIFO depth requirements, and interface protocol support. Verify that replacement parts maintain the required 5V logic levels and PLCC-44 footprint constraints.

Part Context

This part belongs to the XR82C684 series of VLIO UARTs produced by MaxLinear. It serves as a high-density serial interface solution for applications requiring multiple asynchronous channels in a single integrated circuit. The TR suffix indicates tape-and-reel packaging for automated assembly processes.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers must consult official MaxLinear product change notices or datasheets for qualified replacements.
