89HMPEB383ZANQG

Specialized Overview

The 89HMPEB383ZANQG is a PCI Express to PCI bridge interface IC manufactured by Renesas Electronics. It provides a high-performance connection between a single-lane PCI Express link and a 32-bit PCI bus. The device supports PCI interface operation up to 66 MHz. It offers three addressing modes: transparent, opaque, and non-transparent bridging. The component is designed for applications requiring superior performance and low latency in mixed-speed bus architectures.

Specialized Feature Summary

• Provides a bridge from single-lane PCI Express to 32-bit PCI
• Supports transparent, opaque, and non-transparent addressing modes
• Enables low-latency bridging with superior performance
• Operates without power sequencing restrictions

Specialized Applications

• PCI Express to PCI bridge implementations
• Systems requiring non-transparent bridging support
• Mixed-speed bus architecture integration

Specialized Procurement Notes

This component is identified as an End-of-Life (EOL) product. Availability is restricted or discontinued. Verify current status through official Renesas discontinuance notifications before design-in. No new production is expected. Sourcing should focus on existing stock or authorized distributors handling EOL inventory.

Specialized Selection Notes

Select this part when a single-lane PCI Express to 32-bit PCI bridge is required. It is suitable for designs needing flexible addressing modes including non-transparent bridging. Consider the QFN package options if space constraints exist. Ensure compatibility with 66 MHz PCI bus speeds. Evaluate end-of-life status implications for long-term supply chain stability.

Specialized Part Context

The 89HMPEB383ZANQG belongs to the 89HPEB383 family of PCI Express to PCI bridge controllers. These devices are designed to facilitate connectivity between modern PCI Express systems and legacy PCI peripherals. The family typically includes variants with different packaging options such as QFN and QFP, maintaining consistent functional specifications across the series.

Specialized Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the product is marked as End-of-Life, direct replacements may require consulting Renesas for obsolescence management or evaluating alternative bridge solutions with similar interface capabilities.
