QDR II+ adds a separate read and write data port, each clocked at the same frequency, so the controller never has to turn the bus around between read and write cycles. On a standard QDR II part, the address bus is shared and requires a dead cycle to switch direction.
Yes, Cypress has classified the CY7C2565KV18-450BZI as Obsolete. No official replacement part number has been published.
This obsolete part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm position.
72Mbit synchronous QDR II+ SRAM organized 2M x 36, 450 MHz clock, parallel interface, 1.7V to 1.9V supply, -40°C to 85°C operating temperature, 165-FBGA (13x15) package.
QDR II+ uses separate read and write data ports, each clocked at the same frequency, eliminating the bus-turnaround dead cycle that QDR II incurs when switching between read and write on a shared address bus. This sustains full throughput in alternating read/write patterns.
