XR68C192CJTR-F

Overview

The XR68C192CJTR-F is a dual-channel Universal Asynchronous Receiver and Transmitter (UART) interface integrated circuit manufactured by MaxLinear, Inc. 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 supports data rates up to 1 Mb/s. Each channel includes an 8-byte transmit and receive FIFO buffer. It is housed in a 44-pin PLCC package with J-leads, designed for surface-mount installation. The component functions across an industrial temperature range from -40°C to +85°C and draws a typical operating current of 1.5 mA.

Feature Summary

• Dual UART channels with independent operation capabilities
• Integrated 8-byte FIFO buffers for both transmission and reception on each channel
• Internal oscillator eliminates the need for external clock components
• Compatible with multiple supply voltages including 2.5 V, 3.3 V, and 5 V

Applications

• Industrial communication systems requiring robust serial data transfer
• Embedded control units utilizing asynchronous serial interfaces
• Telecommunications equipment needing high-reliability UART connectivity
• Automotive electronic modules operating in extended temperature environments

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance documentation matches specific manufacturing lots. Check for Product Change Notices (PCN) related to assembly site or material changes. Ensure storage conditions adhere to moisture sensitivity level requirements prior to reflow soldering. Validate pin compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component when dual independent UART channels are required in a compact PLCC package. Consider the 8-byte FIFO depth for buffering requirements against higher-capacity alternatives like the XR68C192 series variants. Verify that the 1 Mb/s maximum data rate meets system timing constraints. Ensure the operating voltage range aligns with the target system's power supply rails. Evaluate thermal performance within the specified -40°C to +85°C range for the intended application environment.

Part Context

The XR68C192CJTR-F belongs to the XR68C192 family of dual UART controllers from MaxLinear. This series is derived from legacy CMOS UART designs, offering backward compatibility with older standards while providing modern integration benefits. The 'CJTR' suffix indicates a specific tape-and-reel packaging variant suitable for automated surface-mount assembly processes, distinguishing it from tube-packaged equivalents.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Engineering change notices or discontinuation notifications should be reviewed for potential recommended replacements. Cross-reference pinouts and electrical characteristics with alternative dual UART ICs if sourcing new production units.
