CY7C1353F  
4-Mb (256K x 18) Flow-through SRAM with NoBL™ Architecture  
• Burst Capability—linear or interleaved burst order  
• Low standby power  
Functional Description[1]  
Features  
• Can support up to 133-MHz bus operations with zero  
wait states  
— Data is transferred on every clock  
The CY7C1353F is a 3.3V, 256K x 18 Synchronous  
• Pin compatible and functionally equivalent to ZBT™  
Flow-through Burst SRAM designed specifically to support  
devices  
unlimited true back-to-back Read/Write operations without the  
• Internally self-timed output buffer control to eliminate  
insertion of wait states. The CY7C1353F 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 need to use OE  
• Registered inputs for flow-through operation  
• Byte Write capability  
• 256K x 18 common I/O architecture  
• 2.5V / 3.3V I/O power supply  
• Fast clock-to-output times  
— 6.5 ns (for 133-MHz device)  
— 7.5 ns (for 117-MHz device)  
— 8.0 ns (for 100-MHz device)  
— 11.0 ns (for 66-MHz device)  
• Clock Enable (CEN) pin to suspend operation  
• Synchronous self-timed writes  
• Asynchronous Output Enable  
• JEDEC-standard 100 TQFP package  
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  
suspends operation and extends the previous clock cycle.  
Maximum access delay from the clock rise is 6.5 ns (133-MHz  
device).  
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.  
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.
