XR68C192CJ-F

Overview

The XR68C192CJ-F is a dual universal asynchronous receiver and transmitter (DUART) manufactured by MaxLinear, Inc. It integrates two independent UART channels within a single integrated circuit package. The device supports data rates up to 1 Mb/s and includes 8-byte transmit and receive FIFOs for each channel to enhance throughput efficiency. It operates on supply voltages ranging from 2.97 V to 5.5 V, with typical operation at 3.3 V or 5 V. The component features an internal oscillator and supports Motorola bus compatibility.

Feature Summary

Dual-channel architecture providing two independent serial communication interfaces
Integrated 8-byte FIFO buffers for both transmission and reception per channel
Internal oscillator eliminates the need for external clock components
Supports configurable general-purpose input/output pins

Applications

Industrial control systems requiring multiple serial ports
Embedded computing platforms needing reliable asynchronous communication
Telecommunications equipment utilizing standard UART protocols
Motorola bus compatible system designs

Procurement Notes

Verify current availability status as this component may be subject to discontinuation notices. Confirm RoHS compliance details through official manufacturer documentation before integration. Ensure the specific suffix matches required packaging and temperature grades. Cross-reference pinouts with the latest datasheet to avoid interface mismatches during PCB layout.

Selection Notes

Select this component when a design requires two distinct UART interfaces in a compact form factor. The internal oscillator simplifies board layout by removing external crystal requirements. Verify that the operating voltage range aligns with the target system power rails. Consider the LQFP-44 package dimensions for mechanical fitment constraints.

Part Context

This part belongs to the XR68C192 series of DUARTs produced by MaxLinear. It serves as a successor or alternative to legacy Exar Corporation UART controllers. The device maintains compatibility with standard asynchronous serial protocols while offering enhanced FIFO capabilities compared to older generations without buffer memory.
