Description

The CY7C09449PV is one of the PCI interface controllers in the Cypress Semiconductor PCI-DP™ family. The CY7C09449PV provides a PCI master/target interface with direct connections to many popular microprocessors. CY7C09449PV-AC provides 128K bits of dual-port SRAM that is used as shared memory between the local microprocessor and the PCI bus. An I2O message unit, complete with message queues and interrupt capability, CY7C09449PV-AC is also provided. The CY7C09449PV allows the designer to interface an application to the PCI bus in a straightforward, inexpensive way.
