89HMPEB383ZBEM

Specialized Overview

The 89HMPEB383ZBEM is a PCI interface IC functioning as a PCIe bridge, manufactured by Renesas Electronics. It provides a high-performance connection between single-lane PCI Express and 32-bit PCI buses. The device supports transparent, opaque, and non-transparent addressing modes to offer design flexibility. Its PCI interface operates at frequencies up to 66 MHz. The component is available in QFN and QFP packages, with specific variants including 10mm x 10 mm QFN and 14mm x 14 mm QFP options.

Specialized Feature Summary

• Provides superior performance and low latency for data bridging
• Supports non-transparent bridging functionality
• Eliminates power sequencing restrictions during operation

Specialized Applications

• PCI Express to PCI forward bridging systems
• High-performance embedded system interconnects
• Industrial applications requiring flexible addressing modes

Specialized Procurement Notes

This component is classified as End-of-Life (EOL) by the manufacturer. Availability is restricted, and distributors may not stock this item in all regions. Verification of current supply status and alternative sourcing channels is required before procurement planning. Check official discontinuance notifications for detailed lifecycle information.

Specialized Selection Notes

Select this part when a small footprint bridge from single-lane PCI Express to 32-bit PCI is required. Ensure the design accommodates the specific package dimensions, such as the 10mm x 10 mm QFN or 14mm x 14 mm QFP. Verify that the 66 MHz PCI interface speed meets system timing requirements and that non-transparent bridging support aligns with architectural needs.

Specialized Part Context

The 89HMPEB383 series belongs to Renesas' PCI Interface IC category under Interface ICs. It serves as a legacy solution for integrating older 32-bit PCI peripherals with modern PCI Express host systems. The product line includes variants like the 89HPEB383 and 89HMPEB383ZAEMG8, sharing similar core bridging capabilities but differing in packaging and suffix specifications.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, engineers should consult Renesas for recommended obsolescence management strategies or equivalent newer generation bridge controllers.
