The 89HMPEB383ZAEM8 is a PCI interface IC functioning as a PCI Express to PCI bridge manufactured by Renesas Electronics. It provides a high-performance, low-latency connection between single-lane PCI Express and 32-bit PCI buses. The device supports transparent, opaque, and non-transparent addressing modes, offering design flexibility without power sequencing restrictions. It is available in QFN and QFP packages.
This component is officially designated as End-of-Life (EOL) by the manufacturer. Distribution channels indicate restricted availability or discontinuation. Verification of current stock status and valid sourcing channels is required before procurement planning.
Designers should evaluate alternative bridge controllers due to the EOL status of this part. Compatibility checks for pinout and electrical specifications are necessary when selecting replacement components to ensure seamless integration into existing PCI Express to PCI architectures.
This part belongs to the 89HPEB series of PCI interface ICs. It serves as a bridge solution allowing modern PCI Express peripherals to communicate with legacy 32-bit PCI bus systems. The specific suffix indicates package and tape/reel configuration details defined by the manufacturer.
