The CY7C1148KV18, and CY7C1150KV18 are 1.8 V Synchronous Pipelined SRAMs equipped with DDR II+ architecture. The DDR II+ consists of an SRAM core with advanced synchronous peripheral circuitry. Addresses for read and write are latched on alternate rising edges of the input (K) clock. Write data is registered on the rising edges of both K and K. Read data is driven on the rising edges of K and K. Each address location is associated with two 18-bit words (CY7C1148KV18), or 36-bit words (CY7C1150KV18) that burst sequentially into or out of the device.
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.
