89HPEB383ZAEMGI

Specialized Overview

The 89HPEB383ZAEMGI is a PCI interface IC functioning as a PCIe to PCI bridge. It provides a high-performance, small-footprint connection from a single-lane PCI Express link to a 32-bit PCI bus. The device supports PCI interface operation up to 66 MHz and offers three addressing modes: transparent, opaque, and non-transparent bridging. This flexibility allows designers to manage system architecture without power sequencing restrictions. The component is manufactured by Renesas Electronics.

Specialized Feature Summary

• Provides high-performance bridging between single-lane PCI Express and 32-bit PCI interfaces
• Supports transparent, opaque, and non-transparent addressing modes for design flexibility
• Enables low-latency data transfer with no power sequencing restrictions

Specialized Applications

• Systems requiring expansion of PCI Express upstream ports to legacy PCI peripherals
• Industrial control systems needing non-transparent bridging for isolated domain communication
• Embedded designs constrained by space requiring small footprint bridge solutions

Specialized Procurement Notes

Verify availability status carefully as this specific part number may be subject to discontinuation or limited supply. Check official Renesas documentation for current lifecycle status and alternative sourcing options. Ensure compatibility with existing system requirements before procurement.

Specialized Selection Notes

Select this component when a single-lane PCIe to 32-bit PCI bridge is required. Consider the available addressing modes if system isolation or specific memory mapping is needed. Verify package availability and ensure the design accommodates the specified operating frequency limits.

Specialized Part Context

This device belongs to the 89HPEB series of PCI Express bridges from Renesas. It is designed to facilitate integration of legacy PCI components into modern PCIe-based architectures. The series emphasizes performance and flexibility in system interconnectivity.

Specialized Replacement Considerations

Consult Renesas official documentation for confirmed substitute part numbers. The datasheet indicates potential end-of-life notifications; verify active alternatives through manufacturer channels rather than assuming generic cross-references.
