XR68C192CVTR-F

Overview

The XR68C192CVTR-F is a dual-channel Universal Asynchronous Receiver/Transmitter (DUART) manufactured by MaxLinear, Inc. It features two independent UART channels, each equipped with a 16-byte transmit and receive FIFO buffer to enhance data throughput and reduce CPU overhead. The device supports a maximum data rate of 230.4Kbps and operates within a supply voltage range of 2.97V to 5.5V. It includes automatic hardware flow control capabilities and integrates an internal oscillator. The component is housed in a 44-LQFP package measuring 10x10 mm and utilizes surface-mount technology for PCB integration.

Feature Summary

• Dual-channel architecture providing two independent asynchronous serial communication interfaces
• Integrated 16-byte transmit and receive FIFO buffers per channel to manage data flow efficiently
• Automatic hardware flow control support to prevent data loss during transmission
• Internal oscillator eliminates the need for external clock components

Applications

• Industrial automation systems requiring reliable serial communication
• Embedded control units with multiple peripheral connections
• Telecommunications equipment utilizing standard UART protocols
• Data acquisition modules needing buffered serial input/output

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolescence status. Confirm package marking and pinout alignment with design specifications. Review official Product Change Notices for any manufacturing updates. Ensure environmental compliance documentation matches project requirements. Validate electrical characteristics against system power and signal integrity constraints before finalizing procurement.

Selection Notes

Choose this component when dual independent UART interfaces with FIFO buffering are required. Consider the 2.97V to 5.5V operating range for compatibility with system power rails. Evaluate the 44-LQFP footprint against available PCB space. Assess the 230.4Kbps maximum speed against application baud rate needs. Verify that automatic flow control meets protocol requirements without software intervention.

Part Context

The XR68C192 series belongs to MaxLinear's family of DUART ICs, designed for robust serial communication in embedded environments. This specific model variant includes 16-byte FIFOs, distinguishing it from lower-capacity counterparts like the XR68C92 which offers only 8 bytes. The CVTR suffix indicates the tape-and-reel packaging format suitable for automated assembly processes.

Replacement Considerations

The XR68C192CV-F is a tray-packaged equivalent of the same functional device. The XR68C92 series serves as a lower-capacity alternative if 8-byte FIFOs suffice. Check for cross-compatible parts within the XR17D154 family for single-channel applications.
