Product details

72 Mbit QDR II SRAM at 250 MHz — what the clock and organization mean for the bus

The 250 MHz clock rate means each read and write port can deliver a new data word every 4 ns, giving back-to-back throughput of 18 Gbit/s on the 36-bit data bus. QDR II eliminates the dead bus-turnaround cycles that conventional synchronous SRAMs incur — the separate read and write ports let the controller issue a read and a write in the same clock cycle, which is the defining advantage for high-bandwidth applications like network packet buffers, telecom line cards, and high-end test equipment.

Last Buy — the sourcing decision this part demands

Cypress has issued an end-of-life notice and the final purchase window is open. The 165-FBGA footprint and QDR II protocol are not drop-in compatible with standard synchronous SRAMs.

Package and temperature — board-fit constraints

The 165-ball FBGA (13x15 mm) package uses a fine-pitch array that demands careful PCB layout — the supply decoupling plan and signal-integrity budget for the 250 MHz bus need to be worked out before the board is laid out.

Frequently asked questions

What is the lifecycle status of CY7C1515KV18-250BZC?

CY7C1515KV18-250BZC is in Last Buy status. Cypress has announced the end of production, and the final purchase window is active. Once the last-time-buy period closes, the part will no longer be manufactured.

Is CY7C1515KV18-250BZC compatible with QDR II designs?

Yes. This is a QDR II synchronous SRAM with separate read and write ports, running at 250 MHz. It is designed for QDR II memory controllers and is not pin-compatible with standard synchronous SRAMs or QDR I/QDR IV families.
