Product Summary

The S21152BB is a PCI-to-PCI bridge and is fully compliant with PCI Local Bus Specification, Revision 2.1. The S21152BB is pin-to-pin compatible with the 21052, which is fully compliant with PCI Local Bus Specification, Revision 2.0.The S21152BB provides full support for delayed transactions, enabling buffering of memory read, I/O, and configuration transactions. The S21152BB has separate posted write, read data, and delayed transaction queues with significantly more buffering capability than first-generation bridges. In addition, the S21152BB supports bi-directional buffering of simultaneous multiple posted write and delayed transactions.
