CY7C1356C-250AXCT

The CY7C1356C is 3.3V, 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 CY7C1354C/CY7C1356C are equipped with the advanced (NoBL) logic required to enable consecutive read/write operations with data being transferred on every clock cycle. This feature greatly improves the throughput of data in systems that require frequent write/read transitions. The CY7C1354C/CY7C1356C are pin compatible and functionally equivalent to ZBT devices.

• Pin-compatible and functionally equivalent to ZBT
• Supports 250 MHz bus operations with zero wait states
  • Available speed grades are 250, 200, and 166 MHz
• Internally self-timed output buffer control to eliminate the need to use asynchronous
• Fully registered (inputs and outputs) for pipelined operation
• Byte write capability
• Single 3.3 V power supply (VDD)
• 3.3 V or 2.5 V I/O power supply (VDDQ)
• Fast clock-to-output times
  • 2.8 ns (for 250 MHz device)
• Clock enable (CE/ and OE/?) pin to suspend operation
