XR17C154CV-F

Overview

The XR17C154CV-F is a quad Universal PCI Bus UART manufactured by MaxLinear, Inc. It integrates four independent UART channels within a single integrated circuit. Each channel features a 64-byte FIFO buffer and supports data rates up to 6.25 Mbps. The device operates on a 5V power supply and includes automatic hardware flow control, IrDA encoder/decoder capabilities, and false start bit detection. It is housed in a 144-LQFP surface-mount package with dimensions of 20x20 mm.

Feature Summary

• Integrates four independent UART channels with 64-byte transmit and receive FIFOs for high-throughput serial communication.
• Supports universal PCI bus signaling designs with automatic hardware flow control and programmable hysteresis.
• Includes built-in IrDA encoder and decoder functionality along with false start bit detection for reliable data integrity.

Applications

• PCI-based industrial automation systems requiring multiple serial interfaces
• Telecommunications equipment utilizing RS485 protocols
• Embedded systems needing high-speed asynchronous serial I/O

Procurement Notes

Verify the manufacturer designation as MaxLinear or Exar, as historical branding may vary. Confirm the specific suffix 'F' corresponds to the required environmental or packaging specifications. Ensure the 144-LQFP package footprint matches the design constraints. Check for any end-of-life notices or production change notifications relevant to this component.

Selection Notes

Select this component when a quad-channel UART solution is required for PCI bus architectures. Compare against the XR17D154CV-F if 3.3V operation is necessary instead of 5V. Consider the XR17L154CV for applications where lower power consumption is prioritized over higher data rates. Verify that the 64-byte FIFO size meets the system's buffering requirements.

Part Context

This part belongs to the XR17C154 series of quad PCI UARTs. It is functionally similar to the XR17D154 but differs in operating voltage range. The XR17C154 is designed specifically for 5V PCI bus environments. It shares architectural similarities with other members of the Exar/MaxLinear UART family but offers distinct pinout and electrical characteristics tailored for PCI applications.

Replacement Considerations

The XR17D154CV-F is a related variant offering 3.3V to 5V operation. For PCIe-based replacements, consider the XR17V354IB176-F which provides 256-byte FIFOs. Verify compatibility with existing PCB footprints and voltage levels before substitution.
