XR88C92CVTR-F

Overview

The XR88C92CVTR-F is a dual-channel Universal Asynchronous Receiver/Transmitter (UART) interface integrated circuit manufactured by MaxLinear. It operates within a supply voltage range of 2.97V to 5.5V and supports data rates up to 1 Mb/s. The device features an 8-byte transmit and receive FIFO for each channel, enhancing buffer management efficiency. Packaged in a 44-LQFP format with J-leads, it includes automatic flow control capabilities. Key functional attributes include configurable GPIOs, an internal oscillator, and integrated timers/counters, designed for surface-mount installation.

Feature Summary

• Dual independent UART channels with dedicated 8-byte FIFO buffers for simultaneous data handling
• Integrated automatic hardware flow control to manage data transmission integrity
• Configurable general-purpose input/output pins alongside internal timing and counting functions

Applications

• Industrial communication systems requiring reliable serial data exchange
• Embedded controller interfaces for peripheral device connectivity
• Telecommunications equipment utilizing standard asynchronous protocols

Procurement Notes

Verify component authenticity through authorized distribution channels due to potential availability constraints. Confirm package marking and date codes against current manufacturing notices. Ensure compatibility with existing board layouts regarding the 44-LQFP footprint. Review product discontinuation notifications for long-term supply chain stability before finalizing procurement plans.

Selection Notes

Select this component when dual asynchronous serial ports are required within a single compact package. The 8-byte FIFO depth suits applications with moderate burst traffic rather than high-throughput streaming. Verify that the 44-LQFP package dimensions align with the target PCB design constraints. Consider the operating voltage range to ensure compatibility with the system's power rails.

Part Context

This part belongs to the XR88Cx92 series of VLIO UARTs from MaxLinear. It shares architectural similarities with other variants like the XR88C92CJ-F but differs in packaging and termination style. The series is characterized by low-power CMOS technology and integration of auxiliary functions such as GPIOs and timers within a standard UART framework.

Replacement Considerations

Direct substitutes include the XR88C92CJ-F and XR88C92IJTR-F. These alternatives share identical electrical specifications and pinout configurations. Verify that the specific suffix indicates the correct tape-and-reel packaging if automated assembly is utilized.
