Diodes Incorporated PI7C9X110BNB PCIe-to-PCI Bridge

The PI7C9X110BNB from Diodes Incorporated is a high-performance PCIe-to-PCI bridge chip designed to enable seamless communication between newer PCIe-equipped systems and legacy PCI devices. This bridge chip is an ideal solution for extending the life of PCI-based devices, ensuring compatibility and extending their usability in modern computer architectures.

With its advanced features, the PI7C9X110BNB provides a reliable and efficient bridge interface. It supports a 32-bit, 33/66 MHz PCI interface and can handle the full range of PCIe Gen1 (2.5GT/s) data rates. The bridge chip is capable of forward and reverse bridging, which allows it to facilitate communication in both directions, from PCIe to PCI and vice versa.

The product is designed with a focus on reliability and ease of integration. It is equipped with a primary PCI Express x1 interface, and it complies with the PCI Express Base Specification, Revision 1.1, and the PCI Local Bus Specification, Revision 3.0. This ensures high compatibility with a wide range of devices and systems. Additionally, the PI7C9X110BNB supports both 3.3V and 5V PCI signaling environments, making it versatile for use with various types of legacy PCI devices.

The PI7C9X110BNB also includes several features to enhance performance and usability. It incorporates an efficient packet-based protocol for high-speed data transfers and provides support for PCIe power management, including active state power management (ASPM) and power budgeting. Furthermore, the chip is designed with a transparent mode of operation, which simplifies system design by allowing the PCI devices to appear as if they are directly connected to the PCIe host.

For developers and system integrators, the PI7C9X110BNB is available in a compact 160-pin TQFP package, which minimizes the PCB footprint and is suitable for space-constrained applications. Whether it’s for industrial, embedded, or consumer applications, the PI7C9X110BNB bridge chip is an excellent choice for bridging the gap between new and old interface technologies, ensuring a smooth transition and extended product lifecycles.
