Product details

72 Mbit QDR II+ SRAM — what the 366 MHz clock buys you

The CY7C2564XV18-366BZXC: It is organized as 2M x 36 and clocks at 366 MHz, which means the memory can deliver back-to-back read and write operations on every clock edge without the dead cycles that older NoBL or DDR SRAMs incur. The 13x15 mm footprint is standard for this density tier; plan for a multi-layer PCB with dedicated power planes under the BGA.

It belongs in a controlled indoor environment — server room, central office, test equipment — not on a factory floor or in an outdoor cabinet. If the BOM calls for industrial or automotive temperature, you need a different suffix in the CY7C2564 family.

Package and board-level handling

The 165-ball FBGA (13x15 mm) is a fine-pitch BGA. BGA rework needs a profile that matches the solder-ball alloy.

Frequently asked questions

What does the 366 MHz clock mean for my design?

At 366 MHz, the QDR II+ interface delivers a read and a write on every clock cycle — effectively double the throughput of a single-data-rate SRAM at the same frequency. The 2M x 36 organization gives you 72 Mbits of storage with a 36-bit data bus, which suits wide-word lookup tables or packet buffers that need high sustained bandwidth.
