XR88C192IVTR-F

Overview

The XR88C192IVTR-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 and supports data rates up to 1 Mb/s. The device features 8-byte transmit and receive FIFOs for each channel, enabling efficient data buffering. It is housed in an SOIC-24 surface-mount package and is rated for commercial operating temperatures from 0°C to +70°C. The component includes Intel bus compatibility and offers low power consumption characteristics suitable for embedded serial communication applications.

Feature Summary

• Dual independent UART channels with dedicated 8-byte FIFOs
• Compatible with Intel bus protocols for system integration
• Wide single-supply voltage operation from 2.97 V to 5.5 V

Applications

• Industrial control systems requiring serial communication
• Embedded devices needing multiple asynchronous serial ports
• Data acquisition modules with moderate baud rate requirements

Procurement Notes

This component is officially discontinued by the manufacturer. Verification of availability should focus on surplus distributors or secondary market sources rather than direct factory orders. Buyers must confirm lot dates and authenticity through authorized resellers due to the end-of-life status. Design-in replacements are recommended for new projects to ensure long-term supply stability.

Selection Notes

Select this part only if existing designs require the specific pinout and electrical characteristics of the XR88C192 series. Engineers should evaluate the 8-byte FIFO depth against application throughput needs. Consider the commercial temperature range limitation when deploying in harsh environments. Verify that the required baud rates do not exceed the 1 Mb/s specification for reliable signal integrity.

Part Context

The XR88C192 belongs to the XR88C family of dual-channel UARTs designed for cost-sensitive serial interface applications. It serves as a bridge between parallel microprocessor buses and asynchronous serial lines. The IVTR suffix indicates a tape-and-reel packaging format optimized for automated surface-mount assembly processes.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, engineers should consult MaxLinear's official obsolescence notices for potential cross-reference recommendations or contact technical support for approved alternative components.
