SRAM Chip Sync Dual 2.5V 9M-Bit 512K x 18 3.5ns 100-Pin TQFP

The CY7C1356CV25 is a 2.5 V, 256 K × 36/512 K × 18 synchronous pipelined burst SRAMs with No Bus Latency (NoBL logic, respectively. They are designed to support unlimited true back-to-back read/write operations with no wait states. The CY7C1356CV25 is equipped with the advanced (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 in systems that require frequent write/read transitions. The CY7C1356CV25 are pin-compatible with and functionally equivalent to ZBT devices.
