89HPEB383ZBEM

Specialized Overview

The 89HPEB383ZBEM is a PCI Express to PCI bridge IC manufactured by Renesas Electronics. It provides a high-performance, small-footprint connection between single-lane PCI Express and 32-bit PCI buses. The device supports transparent, opaque, and non-transparent addressing modes for design flexibility. Its PCI interface operates at frequencies up to 66 MHz. The component is available in 10mm x 10mm QFN and 14mm x 14mm QFP packages.

Specialized Feature Summary

• Superior performance with low latency bridging
• Supports non-transparent bridging functions
• Eliminates power sequencing restrictions

Specialized Applications

• PCI Express to PCI system interconnects
• Legacy PCI peripheral integration
• Embedded systems requiring address translation

Specialized Procurement Notes

This component is classified as End-of-Life (EOL) by the manufacturer. Availability is restricted or nonexistent through standard distribution channels. Verification of current stock status and alternative sourcing options is required before procurement planning.

Specialized Selection Notes

Designers should verify package compatibility with existing footprints, specifically the 10mm QFN or 14mm QFP variants. Ensure the target system requires 32-bit PCI interfaces operating at 66 MHz. Consider the impact of EOL status on long-term production viability.

Specialized Part Context

This part belongs to the 89HPEB series of PCI Express bridges. It serves as a legacy interface solution for integrating older PCI components into modern PCIe-based architectures. The series emphasizes compact form factors and flexible addressing modes.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, engineering teams must evaluate functional equivalents from other manufacturers or redesign the interface architecture.
