| CY7C1460AV25 CY7C1462AV25 CY7C1464AV25 36-Mbit 1M x 36/2M x 18/512K x 72 Pipelined SRAM with NoBL Architecture • Pin-compatible and functionally equivalent to ZBT • Supports 250-MHz bus operations with zero wait states Available speed grades are 250, 200 and 167 MHz • Internally self-timed output buffer control to eliminate the need to use asynchronous OE • Fully registered inputs and outputs for pipelined operation • Byte Write capability • 2.5V core power supply • 2.5V/1.8V I/O power supply • Fast clock-to-output times ns for 250-MHz device • Clock Enable CEN pin to suspend operation • Synchronous self-timed writes • CY7C1460AV25, CY7C1462AV25 available in JEDEC-standard lead-free 100-pin TQFP package, lead-free and non-lead-free 165-ball FBGA package. CY7C1464AV25 available in lead-free and non-lead-free 209-ball FBGA package • IEEE JTAG-Compatible Boundary Scan • Burst or interleaved burst order • “ZZ” Sleep Mode option and Stop Clock option Functional Description The CY7C1460AV25/CY7C1462AV25/CY7C1464AV25 are 2.5V, 1M x 36/2M x 18/512 x 72 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 CY7C1460AV25/CY7C1462AV25/CY7C1464AV25 equipped with the advanced NoBL logic required to enable consecutive Read/Write operations with data being trans- ferred on every clock cycle. This feature dramatically improves the throughput of data in systems that require frequent Write/Read transitions. CY7C1460AV25/CY7C1462AV25/CY7C1464AV25 pin-compatible and functionally equivalent to ZBT devices. All synchronous inputs pass through input registers controlled by the rising edge of the clock. All data outputs pass through output registers controlled by the rising edge of the clock. The clock input is qualified by the Clock Enable CEN signal, which when deasserted suspends operation and extends the previous clock cycle. Write operations are controlled by the Byte Write Selects for CY7C1464AV25, for CY7C1460AV25 and for CY7C1462AV25 and a Write Enable WE input. All writes are conducted with on-chip synchronous self-timed write circuitry. Three synchronous Chip Enables CE1, CE2, CE3 and an asynchronous Output Enable OE provide for easy bank selection and output three-state control. In order to avoid bus contention, the output drivers are synchronously three-stated during the data portion of a write sequence.
