XR17D152IMTR-F

Overview

The XR17D152IMTR-F is a high-performance dual-channel Universal Asynchronous Receiver/Transmitter (UART) controller designed for PCI bus systems. It integrates two independent UART channels, each compatible with the 16C550 register set and featuring 64-byte transmit and receive FIFOs with programmable trigger levels. The device supports automatic hardware flow control and includes an IrDA encoder/decoder. It operates on a 32-bit PCI interface compliant with PCI 2.3 specifications, supporting byte, word, and double-word transfers in burst mode. The component functions at supply voltages of 3.3V or 5V and achieves data rates up to 6.25Mbps.

Feature Summary

• Dual-channel architecture with independent 16C550-compatible UART interfaces
• Integrated 64-byte FIFO buffers for both transmission and reception
• PCI 2.3 compliant 32-bit bus interface supporting burst transfer modes
• Built-in IrDA 1.0 encoding and decoding capabilities

Applications

• Industrial automation systems requiring serial communication
• Telecommunications equipment utilizing PCI-based architectures
• Embedded computing platforms needing high-speed serial I/O expansion

Procurement Notes

Verify the specific suffix against official MaxLinear documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with existing PCI slot voltage requirements before integration. Request current lifecycle status confirmation from authorized distributors as older components may face obsolescence risks.

Selection Notes

Select this component when a system requires dual asynchronous serial ports integrated directly onto a PCI bus. It is suitable for applications demanding high throughput via FIFO buffering and strict compliance with legacy PCI standards. Consider alternative solutions if native PCIe or USB connectivity is preferred over traditional PCI bus integration.

Part Context

This part belongs to the XR17D152 series of serial I/O controllers manufactured by MaxLinear, formerly Exar. The series is engineered to provide robust serial communication capabilities within PCI-based embedded systems. The IMTR-F designation typically indicates a specific surface-mount packaging variant optimized for automated assembly processes.

Replacement Considerations

Consult official cross-reference lists for direct pin-compatible alternatives. Verify that any substitute maintains identical 16C550 register compatibility and PCI interface signaling to ensure seamless board-level replacement without firmware modifications.
