CY7C1352G  
4-Mbit (256K x 18) Pipelined SRAM with  
NoBL™ Architecture  
Features  
Functional Description[1]  
• Pin compatible and functionally equivalent to ZBT™  
devices  
The CY7C1352G is a 3.3V, 256K x 18 synchronous-pipelined  
Burst SRAM designed specifically to support unlimited true  
back-to-back Read/Write operations without the insertion of  
wait states. The CY7C1352G is equipped with the advanced  
No Bus Latency™ (NoBL™) logic required to enable consec-  
utive Read/Write operations with data being transferred on  
every clock cycle. This feature dramatically improves the  
throughput of the SRAM, especially in systems that require  
frequent Write/Read transitions.  
• Internally self-timed output buffer control to eliminate  
the need to use OE  
• Byte Write capability  
• 256K x 18 common I/O architecture  
• 3.3V core power supply (VDD  
)
• 2.5V/3.3V I/O power supply (VDDQ  
)
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. Maximum access delay from the clock  
rise is 2.6 ns (250-MHz device).  
• Fast clock-to-output times  
— 2.6 ns (for 250-MHz device)  
• Clock Enable (CEN) pin to suspend operation  
• Synchronous self-timed writes  
• Asynchronous output enable (OE)  
Write operations are controlled by the two Byte Write Select  
(BW[A:B]) and a Write Enable (WE) input. All writes are  
conducted with on-chip synchronous self-timed write circuitry.  
• Available in lead-free 100-Pin TQFP package  
• 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 tri-state control. In order to avoid bus  
contention, the output drivers are synchronously tri-stated  
during the data portion of a write sequence.
