CY7C1353  
256Kx18 Flow-Through SRAM with NoBL™ Architecture  
Features  
Functional Description  
Pin compatible and functionally equivalent to ZBT  
devices MCM63Z819 and MT55L256L18F  
• Supports 66-MHz bus operations with zero wait states  
— Data is transferred on every clock  
The CY7C1353 is a 3.3V 256K by 18 Synchronous-  
Flow-Through Burst SRAM designed specifically to support  
unlimited true back-to-back Read/Write operations without the  
insertion of wait states. The CY7C1353 is equipped with the  
advanced No Bus Latency (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 through the SRAM, especially in systems  
that require frequent Write-Read transitions.The CY7C1353 is  
pin/functionally compatible to ZBT SRAMs MCM63Z819 and  
MT55L256L18F.  
• Internally self-timed output buffer control to eliminate  
the need to use OE  
• Registered inputs for Flow-Through operation  
• Byte Write capability  
• 256K x 18 common I/O architecture  
• Single 3.3V power supply  
All synchronous inputs pass through input registers controlled  
by the rising edge of the clock. The clock input is qualified by  
the Clock Enable (CEN) signal, which when deasserted sus-  
pends operation and extends the previous clock cycle. Maxi-  
mum access delay from the clock rise is 9.0 ns (66-MHz de-  
vice).  
• Fast clock-to-output times  
— 11.0 ns (for 66-MHz device)  
— 12.0 ns (for 50-MHz device)  
— 14.0 ns (for 40-MHz device)  
• Clock Enable (CEN) pin to suspend operation  
• Synchronous self-timed writes  
• Asynchronous Output Enable  
• JEDEC-standard 100 TQFP package  
• Burst Capability—linear or interleaved burst order  
• Low standby power  
Write operations are controlled by the four Byte Write Select  
(BWS  
) and a Write Enable (WE) input. All writes are con-  
[1:0]  
ducted with on-chip synchronous self-timed write circuitry.  
Three synchronous Chip Enables (CE , CE , CE ) and an  
1

asynchronous Output Enable (OE) provide for easy bank se-  
lection 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.
