Overview
The XIO2001IPNP, produced by Texas Instruments, is a PCI Express (PCIe) to PCI bus translation bridge. This single-function bridge is designed to facilitate communication between PCI Express and legacy PCI systems, ensuring compatibility and efficient data transfer. It is fully compliant with the PCI Express to PCI/PCI-X Bridge Specification, Revision 1.0, and the PCI Express Base Specification, Revision 2.0, as well as the PCI Local Bus Specification, Revision 2.3. The XIO2001IPNP supports a ×1 PCI Express link operating at full 250 MB/s packet throughput in each direction, making it suitable for various applications requiring high-speed data transfer and robust error handling.
