Overview
The XR17C158CV-F is a quad-channel Universal Asynchronous Receiver/Transmitter (UART) interface integrated circuit designed for PCI bus applications. It operates with a single 5V power supply and supports data rates up to 6.25 Mbps. The device features 64-byte transmit and receive FIFOs per channel to enhance throughput efficiency. It is housed in a 144-lead Low Profile Quad Flat Package (LQFP) with dimensions of 20x20 mm. The component is rated for commercial operating temperatures ranging from 0°C to +70°C.
Feature Summary
- Supports universal PCI bus signaling designs for seamless integration into PCI-based systems.
- Integrates dual IrDA encoder and decoder capabilities within the UART architecture.
- Includes automatic flow control mechanisms to manage data transmission integrity.
Applications
- PCI-based industrial automation controllers requiring serial connectivity.
- Telecommunications equipment utilizing PCI expansion slots.
- Embedded systems needing multiple asynchronous serial ports on a PCI backbone.
Procurement Notes
Verify component authenticity through authorized MaxLinear distributors or certified secondary market suppliers. Confirm RoHS compliance status via official documentation as regulatory requirements vary by region. Request full datasheets and application notes to ensure compatibility with existing system architectures before procurement.
Selection Notes
Select this component when designing PCI-based systems requiring four independent UART channels. Ensure the design accommodates the 144-LQFP package footprint and thermal requirements. Verify that the 5V logic levels align with the target system's voltage domains. Consider the 6.25 Mbps maximum speed against actual baud rate requirements.
Part Context
This part belongs to the XR17C158 series, which focuses on PCI bus UART solutions. It serves as a bridge between parallel PCI buses and serial communication protocols. The device is distinct from the XR17D158 series, which offers different pin configurations and feature sets for similar interface needs.
Replacement Considerations
The XR17V358IB176-F is listed as a potential replacement option. However, it provides eight channels instead of four and utilizes a different package type. Verify pinout compatibility and electrical specifications carefully before substitution.
