CY7C1351S-133AXC IC SRAM 4.5MBIT PARALLEL 100TQFP Cypress Semiconductor Corp

 

Functional Description

The CY7C1351 is a 3.3V, 128K by 36 Synchronous Flow-Through Burst SRAM designed specifically to support unlimited true back-to-back Read/Write operations without the insertion of wait states. The CY7C1351 is equipped with the advanced No Bus Latency™ (NoBL™) logic required to enable consecutive Read/Write operations with data being transferred on every clock cycle. This feature dramatically improves the throughput of data through the SRAM, especially in systems that require frequent Write/Read transitions. The CY7C1351 is pin/functionally compatible to ZBT SRAMs IDT71V547, MT55L128L36F, and MCM63Z737.
