www.DataSheet4U.com CY7C1470V33 CY7C1472V33 CY7C1474V33 72-Mbit (2M x 36/4M x 18/1M x 72) Pipelined SRAM with NoBL™ Architecture Features • 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 • Single 3.3V power supply • 3.3V/2.5V I/O power supply • Fast clock-to-output time — 3.0 ns (for 250-MHz device) • Clock Enable (CEN) pin to suspend operation • Synchronous self-timed writes • CY7C1470V33, CY7C1472V33 available in JEDEC-standard lead-free 100-pin TQFP, lead-free and non-lead-free 165-ball FBGA package. CY7C1474V33 available in lead-free and non-lead-free 209 ball FBGA package • IEEE 1149.1 JTAG Boundary Scan compatible • Burst capability—linear or interleaved burst order • “ZZ” Sleep Mode option and Stop Clock option Functional Description The CY7C1470V33, CY7C1472V33, and CY7C1474V33 are 3.3V, 2M x 36/4M x 18/1M 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 CY7C1470V33, CY7C1472V33, and CY7C1474V33 are 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 CY7C1470V33, CY7C1472V33, and CY7C1474V33 are 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 (BWa–BWh for CY7C1474V33, BWa–BWd for CY7C1470V33 and BWa–BWb for CY7C1472V33) 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 tri-state control. In order to avoid bus contention, the output drivers are synchronously tri-stated during the data portion of a write sequence.
