89HMPEB383ZBNQ8

Specialized Overview

The 89HMPEB383ZBNQ8 is a PCI Express to PCI bridge IC manufactured by Renesas Electronics. It provides a high-performance, small-footprint solution for converting single-lane PCI Express signals to 32-bit PCI interfaces. The device supports multiple addressing modes including transparent, opaque, and non-transparent bridging, offering design flexibility. Its PCI interface operates at frequencies up to 66 MHz. The component is available in QFN and QFP packages, facilitating integration into systems requiring robust interconnectivity between modern PCIe buses and legacy PCI peripherals without power sequencing restrictions.

Specialized Feature Summary

• Supports non-transparent bridging for enhanced system isolation
• Enables flexible addressing through transparent, opaque, and non-transparent modes
• Operates with no power sequencing restrictions for simplified design

Specialized Applications

• Systems requiring conversion from single-lane PCI Express to 32-bit PCI
• Industrial control equipment needing low-latency bridging
• Embedded systems integrating legacy PCI peripherals with modern host architectures

Specialized Procurement Notes

Verify the exact suffix ZBNQ8 against official Renesas documentation to confirm package type and temperature range. Confirm end-of-life status as similar variants are discontinued. Request current availability directly from authorized distributors or the manufacturer. Ensure RoHS compliance details match specific regional requirements before procurement.

Specialized Selection Notes

Select this component when a single-lane PCIe to 32-bit PCI bridge is required. Consider the 10mm x 10mm QFN or 14mm x 14mm QFP options based on board space constraints. Evaluate thermal management needs for the chosen package. Verify that the 66 MHz PCI speed meets system timing requirements. Compare against newer bridge solutions if future-proofing is necessary.

Specialized Part Context

This part belongs to the 89HPEB383 family of PCI Express to PCI bridges. It shares core functionality with variants like 89HMPEB383ZAEMG8 but differs in packaging and suffix specifications. The family is designed for high-performance bridging applications. Check datasheets for pin compatibility across the series. Note that some family members may have different discontinuation statuses.
