XR68C92IJTR-F

Overview

The XR68C92IJTR-F is a dual-channel Universal Asynchronous Receiver and Transmitter (UART) interface integrated circuit manufactured by MaxLinear. It operates within a supply voltage range of 2.97 V to 5.5 V, supporting standard logic levels of 2.5 V, 3.3 V, and 5 V. The device features an internal oscillator and provides 8 bytes of transmit and receive FIFO storage per channel. It supports data rates up to 1 Mb/s and functions reliably across an industrial temperature range from -40°C to +85°C. The component is housed in a 44-pin PLCC package with J-leads and is supplied in tape and reel format for surface-mount assembly.

Feature Summary

• Dual independent UART channels with dedicated 8-byte transmit and receive FIFOs for efficient data buffering
• Integrated internal oscillator eliminates the need for external clock components
• Supports multiple supply voltages including 2.5 V, 3.3 V, and 5 V for broad system compatibility

Applications

• Industrial communication systems requiring robust serial data transmission
• Embedded control units utilizing asynchronous serial interfaces
• Telecommunications equipment needing reliable UART connectivity

Procurement Notes

This component has reached End-of-Life status. Verify availability through authorized distributors or secondary market suppliers. Confirm RoHS compliance and specific manufacturing lot dates upon acquisition. Ensure proper handling procedures are followed due to moisture sensitivity classification. Review Product Change Notices for any updates regarding packaging or material composition changes prior to integration.

Selection Notes

Select this part when a dual-channel UART solution with integrated FIFOs is required in a PLCC package. Consider the 1 Mb/s maximum data rate and 8-byte buffer depth against application throughput needs. Verify that the 44-pin footprint matches the PCB layout constraints. Evaluate power consumption requirements against the specified operating current at the target supply voltage.

Part Context

The XR68C92IJTR-F belongs to the XR68C192 series of UART interface ICs. It shares functional similarities with other dual-channel UARTs like the XR68C92CJTR-F but differs in packaging and reel configuration. This model specifically utilizes a tape-and-reel package suitable for automated surface-mount placement, distinguishing it from tube-packaged variants.

Replacement Considerations

Direct substitutes include the XR68C92CJTR-F, which offers identical electrical specifications but in a cut-tape or reel format. The XR68C92CV-F serves as a pin-compatible alternative in an LQFP-44 package. Verify pinout compatibility and thermal characteristics before substituting.
