Product details

The Infineon CY7C25652KV18-400BZC is a 72 Mbit QDR II+ synchronous SRAM organised as 2M x 36. It clocks at 400 MHz on a parallel interface, running from a 1.7 V to 1.9 V supply. The QDR II+ architecture eliminates bus-turnaround dead cycles, delivering back-to-back read and write throughput at the full clock rate — critical for high-bandwidth packet buffers in networking switches and for FPGA-based data accelerators that cannot tolerate a dead cycle between transactions.

Housed in a 165-FBGA (13x15 mm), the package footprint is shared across the CY7C25652 density family.

Frequently asked questions

What replaces CY7C25652KV18-400BZC if I need a higher clock rate?

The CY7C25652KV18-500BZC runs at 500 MHz and the CY7C2565XV18-633BZC runs at 633 MHz — both are 72 Mbit QDR II+ SRAMs in the same 165-FBGA footprint with the same 1.7 V to 1.9 V supply and 2M x 36 organisation. They are drop-in compatible for a clock-rate upgrade without board rework.

What is the package type for CY7C25652KV18-400BZC?

The part ships in a 165-FBGA (13x15 mm) package with a 1.0 mm ball pitch, surface-mount only.
