Clocked at 333 MHz, it delivers back-to-back read and write operations on separate ports without bus-turnaround dead cycles — the whole point of the QDR (Quad Data Rate) family. The 36-bit word width maps directly to a 36-bit data bus on a networking ASIC or FPGA, common in line-card buffer applications where every nanosecond of latency matters.
The CY7C25652KV18-500BZC is a 500 MHz variant with the same 72 Mbit density, 2M x 36 organization, 1.7–1.9 V supply, and 165-FBGA footprint. It is a functional speed-grade upgrade, not an official Cypress-specified replacement, but it is pin-compatible and electrically compatible at the same supply voltage.
Rated for 0°C to 70°C (commercial grade). Not suitable for extended-temperature or outdoor environments.
