CY7C1460AV25  
CY7C1462AV25  
CY7C1464AV25  
36-Mbit (1M x 36/2M x 18/512K x 72)  
Pipelined SRAM with NoBL™ Architecture  
Functional Description  
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  
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  
• Internally self-timed output buffer control to eliminate  
the need to use asynchronous OE  
CY7C1460AV25/CY7C1462AV25/CY7C1464AV25  
are  
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  
• Fully registered (inputs and outputs) for pipelined  
operation  
• Byte Write capability  
• 2.5V core power supply  
Write/Read  
transitions.  
The  
CY7C1460AV25/CY7C1462AV25/CY7C1464AV25  
pin-compatible and functionally equivalent to ZBT devices.  
are  
• 2.5V/1.8V I/O power supply  
• Fast clock-to-output times  
— 2.6 ns (for 250-MHz device)  
• Clock Enable (CEN) pin to suspend operation  
• Synchronous self-timed writes  
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 CY7C1464AV25,  
BWa–BWd for CY7C1460AV25 and BWa–BWb for  
CY7C1462AV25) and a Write Enable (WE) input. All writes are  
conducted with on-chip synchronous self-timed write circuitry.  
• 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 1149.1 JTAG-Compatible Boundary Scan  
• Burst capability—linear or interleaved burst order  
• “ZZ” Sleep Mode option and Stop Clock option  
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.
