XR68C192CV-F

Overview

The XR68C192CV-F is a dual-channel UART interface integrated circuit manufactured by MaxLinear, Inc. It operates within a 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 and utilizes an LQFP-44 package. It is designed for serial communication applications requiring Motorola bus compatibility.

Feature Summary

• Dual independent UART channels with 8-byte FIFOs
• Compatible with Motorola bus signaling
• Operates on 3.3 V or 5 V supply rails

Applications

• Industrial control systems
• Telecommunications equipment
• Embedded serial communication interfaces

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer direct channels. Confirm RoHS compliance status and check for recent Product Change Notices (PCNs) regarding manufacturing site changes. Ensure the specific suffix matches required packaging and temperature grades before procurement.

Selection Notes

Select this component when dual asynchronous serial ports are required in a compact surface-mount package. Verify that the system logic levels align with the 3.3 V or 5 V operating voltage. Ensure the design accommodates the LQFP-44 footprint and thermal requirements for the commercial temperature range.

Part Context

This part belongs to the XR68C192 series of VLIO UARTs from MaxLinear. It serves as a legacy-compatible solution for systems originally designed around MC68681 or similar dual UART controllers. The series provides reliable serial I/O expansion for embedded applications.

Replacement Considerations

Check for pin-to-pin compatible alternatives within the MaxLinear portfolio if availability is constrained. Verify electrical parameter equivalence for any cross-brand substitutes to ensure signal integrity and timing compliance.
