89HPEB383ZAEM

Specialized Overview

The 89HPEB383ZAEM is a PCI interface IC functioning as a PCIe bridge, manufactured by Renesas Electronics. It provides a high-performance, small-footprint bridge from single-lane PCI Express to a 32-bit PCI bus. The device supports three addressing modes: transparent, opaque, and non-transparent. 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 for data transfer
• Supports non-transparent bridging functionality
• Eliminates power sequencing restrictions during operation

Specialized Applications

• PCI Express to PCI system interconnect bridges
• High-performance I/O expansion systems
• Embedded devices requiring flexible addressing modes

Specialized Procurement Notes

Verify the specific suffix ZAEM against official documentation to confirm package type and temperature grade. Confirm end-of-life status and discontinuance notifications prior to procurement planning. Ensure compatibility with existing design constraints regarding the 10mm or 14mm package options.

Specialized Selection Notes

Select this component when a single-lane PCIe upstream connection requires translation to a 32-bit PCI downstream interface. Consider the 66 MHz PCI clock limit and available addressing modes. Evaluate package size requirements between the 10mm QFN and 14mm QFP options based on board space constraints.

Specialized Part Context

This part belongs to the 89HPEB series of PCI Express bridges. It serves as an interface solution connecting modern PCIe architectures with legacy 32-bit PCI buses. The series emphasizes low latency and flexible configuration for system designers.

Specialized Replacement Considerations

Check for direct pin-compatible substitutes within the same family. Verify if newer generations offer backward compatibility. Consult manufacturer notices for recommended alternative components if this part is discontinued.
