Product details

72Mbit QDR II+ SRAM at 500 MHz — what the clock rate means for the bus

The Cypress CY7C25632KV18-500BZC is a 72Mbit synchronous QDR II+ SRAM organized as 4M×18, clocked at 500 MHz. That clock rate sets the read/write throughput for the memory bus — at 500 MHz, the QDR II+ architecture delivers back-to-back transactions on both clock edges, eliminating the dead cycles a standard SRAM would incur during bus-turnaround. For a line buffer in a network switch or a cache in a test instrument, that means the memory keeps up with the data rate without inserting wait states.

Temperature grade and environment — indoor only

That limits it to indoor, temperature-controlled environments — server rooms, lab equipment, telecom central offices with HVAC. Same 4M×18 organization, same 165-FBGA footprint, but the extended temperature range adds margin for thermal cycling and ambient heat.

Package and footprint — 165-FBGA (13x15)

The 165-FBGA package measures 13x15 mm.

Frequently asked questions

Will CY7C25632KV18-500BZC drop into a board laid out for CY7C25632KV18-550BZC?

Yes, the 500 MHz and 550 MHz variants share the same 165-FBGA (13x15) footprint and the same 4M×18 organization. The only difference is the maximum clock rate — 500 MHz vs 550 MHz. If the board's timing closure was validated at 500 MHz, the -500BZC is a drop-in replacement.
