CY7C1392KV18, CY7C1393KV18: 18-Mbit DDR II SIO SRAM Two-Word Burst Architecture
18-Mbit DDR II SIO SRAM Two-Word Burst Architecture
- 18 Mbit density (2 M x 8, 1 M x 18)
- 333-MHz clock for high bandwidth
- Two-word burst for reducing address bus frequency
- Double data rate (DDR) interfaces (data transferred at 666 MHz) at 333 MHz

The CY7C1392KV18 and CY7C1393KV18 are 1.8 V Synchronous Pipelined SRAMs, equipped with DDR II SIO (double data rate separate I/O) architecture. The DDR II SIO consists of two separate ports: the read port and the write port to access the memory array. The read port has data outputs to support read operations and the write port has data inputs to support write operations. The DDR II SIO has separate data inputs and data outputs to completely eliminate the need to ‘turnaround’ the data bus required with common I/O devices. Access to each port is accomplished through a common address bus. Addresses for read and write are latched on alternate rising edges of the input (K) clock.
Dear valued customer,
Thank you for choosing our products. They come with all the know-how and passion that our engineers have put into it. As you probably already know, Cypress is now Infineon. This is a major step for our company, but also for the good of you.
Reliability and business continuity are of utmost importance for us. Hence, we remain fully committed to honoring existing customer and distributor relationships. This includes offering the legacy Cypress product portfolio. We thank you very much for your trusting support.
