XR17D152IM-F

Overview

The XR17D152IM-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. The device supports a 32-bit PCI interface compliant with PCI 2.3 specifications, enabling byte, word, and double-word transfers along with burst read/write modes. It operates at a maximum clock frequency of 50 MHz and supports data rates up to 0.78125 MBps. The component utilizes a TQFP-100 package.

Feature Summary

• Dual-channel architecture with 16C550 compatibility and 64-byte FIFOs per channel
• PCI 2.3 compliant 32-bit interface supporting burst transfer modes
• Integrated IrDA 1.0 encoder/decoder and programmable baud rate generator
• Supports automatic hardware flow control and software flow control

Applications

• High-speed serial communication interfaces in PCI-based embedded systems
• Industrial automation controllers requiring multiple asynchronous serial ports
• Telecommunications equipment utilizing PCI expansion slots
• Data acquisition systems needing reliable UART connectivity

Procurement Notes

Verify the specific suffix 'F' against official MaxLinear documentation to confirm material composition or lead-free status, as suffixes can indicate manufacturing variations. Ensure the source document explicitly defines this suffix's impact on electrical characteristics or environmental compliance before finalizing procurement specifications.

Selection Notes

Select this component when a design requires dual UART channels integrated directly onto a PCI bus without external bridge controllers. It is suitable for applications demanding high throughput via burst mode operations and strict adherence to standard UART register sets for legacy software compatibility. Verify that the system provides a 32-bit PCI slot and appropriate voltage levels for operation.
