89HMPEB383ZAEMGI

Specialized Overview

The 89HMPEB383ZAEMGI is a PCI interface IC functioning as a PCI Express to PCI forward bridge, manufactured by Renesas Electronics. It bridges single-lane PCI Express to a 32-bit PCI bus, with the PCI interface supporting operation up to 66 MHz. The device supports transparent, opaque, and non-transparent addressing modes for design flexibility. It is available in QFN and QFP packages and is designated as an End-of-Life product.

Specialized Feature Summary

• Provides high-performance bridging from single-lane PCI Express to 32-bit PCI
• Supports transparent, opaque, and non-transparent addressing modes
• Enables low-latency data transfer without power sequencing restrictions

Specialized Applications

• System interconnects requiring PCI Express to legacy PCI conversion
• Industrial control systems utilizing mixed bus architectures
• Embedded computing platforms needing compact bridge solutions

Specialized Procurement Notes

This component is officially classified as End-of-Life (EOL) by Renesas Electronics. Verification of availability should focus on distributor surplus or secondary market sources rather than direct manufacturer allocation. Buyers must confirm authenticity through authorized channels due to the discontinued status and potential for obsolete stock circulation.

Specialized Selection Notes

Designers should evaluate the 89HPEB383 series for functional equivalence, noting that this specific suffix variant is discontinued. Considerations include package compatibility and thermal requirements. Alternative modern bridge controllers may offer enhanced performance but require schematic and firmware adaptation for pin-compatible replacement.

Specialized Part Context

The 89HMPEB383ZAEMGI belongs to the IDT/Renesas 89HPES family of high-performance PCI Express to PCI bridges. This series was designed to facilitate integration of PCIe peripherals into existing PCI-based system architectures. The part represents a specialized interface solution prior to the industry-wide transition to native PCIe-only designs.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Renesas official obsolescence notices for recommended migration paths or equivalent current-generation bridge controllers.
