Working Principles

The CY7C09289V-9AXI operates based on the principles of synchronous dual-port RAM. It utilizes a system clock to synchronize read and write operations. The address inputs determine the memory location being accessed, while the data inputs/outputs facilitate data transfer between the IC and external systems.

When a read operation is initiated, the addressed data is retrieved from the specified memory location and made available at the corresponding data output pins. Similarly, during a write operation, the incoming data is stored in the designated memory location.

The chip enables, output enables, and write enables control the access and functionality of each port, ensuring simultaneous and independent operations.
