CY7C1355B  
CY7C1357B  
9-Mb (256K x 36/512K x 18) Flow-Through  
SRAM with NoBL™ Architecture  
• JTAG boundary scan for BGA and fBGA packages  
• Burst Capability—linear or interleaved burst order  
Features  
• No Bus Latency™ (NoBL™) architecture eliminates  
• Low standby power  
dead cycles between write and read cycles.  
Functional Description[1]  
• Can support up to 133-MHz bus operations with zero  
wait states  
— Data is transferred on every clock  
The CY7C1355B/CY7C1357B is a 3.3V, 256K x 36/ 512K x 18  
Synchronous Flow-through Burst SRAM designed specifically  
to support unlimited true back-to-back Read/Write operations  
• Pin compatible and functionally equivalent to ZBT™  
devices  
without  
the  
insertion  
of  
wait  
states.  
The  
• Internally self-timed output buffer control to eliminate  
the need to use OE  
• Registered inputs for flow-through operation  
• Byte Write capability  
• 3.3V/2.5V I/O power supply  
• Fast clock-to-output times  
— 6.5 ns (for 133-MHz device)  
— 7.0 ns (for 117-MHz device)  
— 7.5 ns (for 100-MHz device)  
CY7C1355B/CY7C1357B 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.  
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 or four Byte Write  
Select (BWX) 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.  
• Clock Enable (CEN) pin to enable clock and suspend  
operation  
• Synchronous self-timed writes  
• Asynchronous Output Enable  
• OfferedinJEDEC-standard100TQFP,119-BallBGAand  
165-Ball fBGA packages  
• Three chip enables for simple depth expansion.  
• Automatic Power-down feature available using ZZ  
mode or CE deselect.
