Product details

550 MHz QDR II+ SRAM for high-throughput buffers

The 550 MHz clock rate delivers back-to-back read/write transactions without dead cycles, which matters for network packet buffers, switch look-up tables, and high-speed DSP memory where every bus cycle counts. The 36-bit word width accommodates 32-bit data plus 4-bit parity or ECC, a common choice in telecom line-card designs. Supply voltage runs from 1.7V to 1.9V, aligning with 1.8V-core logic families.

Industrial temperature and package — fit for outdoor and factory environments

The 165-FBGA (15x17 mm) is a fine-pitch BGA — standard for high-density SRAMs.

Frequently asked questions

What is the clock speed of CY7C2665KV18-550BZI?

The clock frequency is 550 MHz. At this rate the QDR II+ interface sustains back-to-back read and write operations without bus-turnaround dead cycles.

What is the memory organization of CY7C2665KV18-550BZI?

Organized as 4M words by 36 bits (4M x 36), totalling 144 Mbit. The 36-bit width supports 32-bit data plus 4-bit parity or ECC.

Are there alternatives to CY7C2665KV18-550BZI?

Pin-compatible alternatives exist within the same Cypress QDR II+ family at different density or speed grades (e.g., 72 Mbit or 288 Mbit variants with the same footprint). For a specific alternate order code, check the base product number CY7C2665 and the QDR II+ family selection guide.
