Product details

550 MHz DDR II+ SRAM for high-throughput line cards

The Cypress CY7C1570KV18-550BZXC is a 72Mbit synchronous SRAM using DDR II+ architecture, organized as 2M x 36. Its 550 MHz clock rate delivers back-to-back read/write throughput without dead cycles, making it a fit for network switch buffers, telecom line cards, and high-end test equipment that need low-latency, high-bandwidth data storage.

Package and supply — what fits the board

The supply range is 1.7V to 1.9V — a narrow, low-voltage rail that demands tight regulation and adequate decoupling, typically a 1.8V rail with ±5% tolerance.

Frequently asked questions

What is the memory organization and clock speed of this SRAM?

It is organized as 2M x 36 (72Mbit total) and operates at a 550 MHz clock frequency using a DDR II+ synchronous interface, enabling high-throughput, low-latency data access.
