XR68C92CJ-F

Overview

The XR68C92CJ-F is a dual-channel UART interface integrated circuit manufactured by MaxLinear, Inc. It operates within a supply voltage range of 2.97 V to 5.5 V and supports data rates up to 1 Mb/s. The device features 8-byte transmit and receive FIFOs for each channel. It is housed in a PLCC-44 package with surface mount installation. The component functions across an operating temperature range of 0°C to +70°C.

Feature Summary

• Dual independent UART channels with dedicated 8-byte transmit and receive FIFOs
• Supports Motorola bus compatibility for system integration
• Operates on standard 3.3 V or 5 V power supplies

Applications

• Industrial serial communication systems
• Embedded control interfaces requiring dual asynchronous ports
• Motorola-bus compatible hardware platforms

Procurement Notes

Verify the specific suffix against official MaxLinear documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status through current datasheets. Check for active discontinuation notices as this series may be subject to end-of-life management protocols.

Selection Notes

Select this component when dual asynchronous serial ports are required with moderate buffering capabilities. Ensure the target system utilizes Motorola bus signaling standards. Verify that the available PLCC-44 footprint matches the PCB layout constraints and that the operating temperature range meets environmental requirements.

Part Context

This part belongs to the VLIO UART product line from MaxLinear. It serves as a legacy interface solution for systems requiring reliable asynchronous serial connectivity. The device bridges microprocessor buses to external serial peripherals using standard UART protocols.

Replacement Considerations

Consult official substitution guides for direct replacements. Consider the XR68C92CV-F for LQFP-44 packaging variants. Evaluate newer MaxLinear UART families if advanced features or different form factors are required.
