XR68C92CVTR-F

Overview

The XR68C92CVTR-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 both 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 asynchronous communication protocols with a maximum data transfer rate of 1 Mb/s and a maximum clock frequency of 24 MHz. The component is housed in a 44-pin LQFP package (10x10 mm) and is designed for surface-mount installation. It includes low-power operating modes and complies with RoHS standards.

Feature Summary

• Dual independent UART channels with dedicated 8-byte TX and RX FIFOs
• Supports Motorola bus interface compatibility
• Operates across 3.3 V and 5 V power supply ranges
• Includes low-power mode functionality

Applications

• Industrial control systems requiring serial communication
• Embedded systems with multiple UART interfaces
• Telecommunications equipment
• Data acquisition modules

Procurement Notes

Verify the exact part number suffix against official MaxLinear documentation, as variations such as 'CV' versus 'CVTR' indicate different packaging formats. Confirm current availability status, as this specific variant may be subject to discontinuation or limited supply conditions. Ensure compliance with moisture sensitivity level requirements during storage and handling procedures prior to assembly.

Selection Notes

Select this component when dual synchronous serial ports are required within a single IC footprint. Consider the 8-byte FIFO depth for buffer management needs. Verify that the 24 MHz clock limit and 1 Mb/s data rate meet system timing constraints. Ensure the design accommodates the LQFP-44 thermal dissipation characteristics and pinout configuration.

Part Context

This part belongs to the XR68C192 series of VLIO UARTs from MaxLinear. It is functionally related to variants like the XR68C92CV-F and XR68C92CJTR-F, differing primarily in packaging type. The series is designed for high-performance serial I/O applications in embedded environments.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with other XR68C92 variants only if packaging differences are acceptable and functional equivalence is verified through official datasheets.
