XR68C92CV-F

Overview

The XR68C92CV-F is a dual-channel UART interface integrated circuit manufactured by MaxLinear. It operates within a supply voltage range of 2.97 V to 5.5 V, supporting standard 3.3 V and 5 V logic levels. The device features an 8-byte transmit and receive FIFO for each channel, enabling efficient data buffering. It supports data rates up to 1 Mb/s and includes Motorola bus compatibility. The component is housed in a 44-pin LQFP package suitable for surface mount technology. It functions within an industrial temperature range from 0°C to +70°C.

Feature Summary

• Dual independent UART channels with dedicated 8-byte FIFOs for both transmission and reception.
• Supports Motorola bus protocol alongside standard asynchronous serial communication.
• Integrated low-power mode capability to reduce energy consumption during idle states.
• CMOS construction allowing operation across a wide voltage range including 3.3V and 5V systems.

Applications

• Industrial control systems requiring reliable serial communication interfaces.
• Embedded devices utilizing Motorola bus architecture for peripheral connectivity.
• Data acquisition systems needing buffered serial I/O for multiple channels.

Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Distribution availability is restricted, and Mouser indicates non-availability in certain regions. Verification of current stock status through authorized distributors or secondary market suppliers is essential before design finalization. Ensure compliance with RoHS directives if applicable to the specific revision.

Selection Notes

Designers should consider the EOL status when selecting this part for new products. Verify that the 44-pin LQFP footprint matches the target PCB layout constraints. Confirm that the 8-byte FIFO depth meets the system's throughput requirements at the desired baud rate. Check humidity sensitivity classification for proper storage and handling procedures during assembly.

Part Context

The XR68C92CV-F belongs to the XR68C192 series of VLIO UARTs. It is functionally related to other variants such as the XR68C92CJTR-F, which differs primarily in packaging format. The device serves as a serial I/O controller compatible with legacy protocols while offering modern CMOS integration benefits for embedded applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, alternative solutions require careful evaluation of pin compatibility and feature parity. Consult manufacturer obsolescence notices for potential recommended replacements.
