Cypress Semiconductor Corp. Memory CY7C1353B-66AC

The CY7C1353B-66AC is a 256K x 18 Synchronous Flow-Through SRAM from Quarktwin Technology Ltd., designed to operate at a clock speed of 66 MHz with a maximum access time of 11 ns. This memory device features No Bus Latency (NoBL,Ñ¢) architecture, allowing for continuous read/write operations without wait states, which enhances data throughput in applications requiring frequent transitions between read and write operations. The device operates on a single 3.3V power supply and is pin-compatible with ZBT,Ñ¢ SRAMs, making it suitable for various applications. It includes registered inputs for flow-through operation, byte write capability, and supports burst operations in both linear and interleaved modes. The CY7C1353B-66AC is housed in a 100-lead TQFP package, facilitating integration into compact designs. Engineers considering this product should note its low standby power consumption and the synchronous self-timed write capability, which simplifies control logic in high-speed applications.
