89HPEB383ZAEMG

Specialized Overview

The 89HPEB383ZAEMG is a PCI Express to PCI bridge IC manufactured by Renesas Electronics. It provides a high-performance, small-footprint bridge from a single-lane PCI Express interface to a 32-bit PCI bus. The device supports three addressing modes: transparent, opaque, and non-transparent bridging. Its PCI interface operates at frequencies up to 66 MHz. The component is available in specific package configurations including a 10mm x 10mm QFN and a 14mm x 14mm QFP.

Specialized Feature Summary

• Supports non-transparent bridging for system isolation
• Eliminates power sequencing restrictions between domains
• Provides superior performance with low latency

Specialized Applications

• PCI Express to PCI system interconnect bridges
• I/O expansion systems requiring address translation
• Legacy PCI peripheral integration into PCIe platforms

Specialized Procurement Notes

Verify the exact suffix configuration against official documentation, as variations such as ZAEMG8 indicate specific packaging or material compliance details. Confirm current lifecycle status, as this model may be subject to discontinuation notices. Ensure compatibility with required voltage levels and thermal specifications before procurement.

Specialized Selection Notes

Select this component when a single-lane PCIe connection must interface with a standard 32-bit PCI bus. Consider the supported addressing modes if complex memory mapping is required. Evaluate the physical package constraints, specifically the 10mm QFN or 14mm QFP options, against the target PCB layout requirements.

Specialized Part Context

This part belongs to the 89HPEB series of PCI Express to PCI bridges. It serves as a critical interface solution for connecting modern PCIe architectures with legacy PCI peripherals. The series is designed to offer flexibility through multiple addressing modes while maintaining low latency and high throughput for data transfers.

Specialized Replacement Considerations

Check for updated Renesas or IDT bridge components with similar lane counts and interface specifications. Verify that any substitute supports the same 32-bit PCI frequency and addressing modes. Ensure pinout compatibility if a direct drop-in replacement is required.
