Overview
The XR17D154IV is an 8-channel Universal PCI Bus UART interface integrated circuit manufactured by MaxLinear. It operates within a supply voltage range of 4.5 V to 5.5 V, with a nominal operating voltage of 5 V and a typical working power current of 5 mA. The device supports data rates up to 6.25 Mb/s and includes 64 bytes of storage capacity per channel. It is designed for surface mount installation in an LQFP-144 package. The component functions across a temperature range from -40°C to +85°C and features universal PCI bus signaling designs.
Feature Summary
- Supports eight independent UART channels for multi-port serial communication
- Integrates 64-byte FIFO buffers to manage data flow efficiently
- Compatible with universal PCI bus signaling standards
Applications
- Industrial control systems requiring multiple serial interfaces
- Telecommunications equipment utilizing PCI bus architectures
- Embedded systems needing high-speed serial data transmission
Procurement Notes
Verify the specific suffix IV against official MaxLinear documentation to confirm the industrial temperature grade (-40°C to +85°C) and pinout configuration. Confirm end-of-life status and availability through authorized distributors, as this component may be discontinued or subject to limited supply constraints.
Selection Notes
Select the XR17D154IV when designing systems that require eight UART ports on a single PCI bus interface. Ensure the design accommodates the LQFP-144 package dimensions and thermal requirements for the specified operating temperature range. Verify compatibility with the host system's PCI signaling levels and voltage specifications before integration.
Part Context
This component belongs to the XR17C158/XR17D158 family of PCI UARTs from MaxLinear. It shares functional similarities with the XR17C158CV-F but differs in operating temperature range and specific suffix designations. The part serves as a bridge between parallel PCI buses and asynchronous serial communication protocols.
Replacement Considerations
The XR17V358IB176-F is listed as a possible replacement. Note that this substitute offers 256-byte FIFOs and PCIe support, differing significantly from the original PCI-based design.
