XR17D154CV-F

Overview

The XR17D154CV-F is a quad Universal Asynchronous Receiver and Transmitter (UART) designed for PCI bus applications. It supports both 3.3V and 5V operation with auto-sensing capability. The device features four independent channels, each equipped with 64-byte transmit and receive FIFOs. It operates at data rates up to 6.25 Mb/s within a temperature range of 0°C to +70°C. Power consumption is specified at 4 mA typical operating current. The component utilizes a 144-pin LQFP package and includes integrated IrDA encoder/decoder functionality.

Feature Summary

Supports universal PCI bus signaling with auto-sense for 3.3V or 5V target voltage operation
Provides four independent UART channels with 64-byte FIFOs per channel
Includes a global interrupt source register for efficient status indication across all channels
Integrates IrDA encoder/decoder and automatic hardware/software flow control mechanisms

Applications

Universal Form Factor PCI Bus Add-in Cards
Remote Access Servers
Ethernet Network to Serial Port Bridges

Procurement Notes

Verify the End-of-Life (EOL) status before procurement as the component may be discontinued. Confirm that the 144-LQFP package dimensions match the design footprint. Ensure the 0°C to 70°C commercial temperature range meets system requirements. Validate compatibility with existing PCI bus architectures given the specific signaling standards.

Selection Notes

Select this component when a quad-channel PCI UART solution is required. Compare against the XR17C158 if eight channels are needed instead of four. Consider the XR17V354IB176-F for PCIe-based designs requiring higher performance. Verify that the 64-byte FIFO depth is sufficient for the intended throughput without excessive buffering.

Part Context

This part belongs to the XR17D154 series of PCI bus UARTs manufactured by MaxLinear. It shares pinouts with related models like the XR17C158 and XR17D158. The device is part of the legacy Exar product line now managed under the MaxLinear portfolio. It serves as a bridge between PCI buses and serial communication interfaces.
