CY7C1475V33  
72-Mbit (2M x 36/4M x 18/1M x 72)  
Flow-ThroughSRAMwithNoBL™Architecture  
Functional Description [1]  
Features  
• No Bus Latency™ (NoBL™) architecture eliminates dead  
cycles between write and read cycles  
The CY7C1471V33, CY7C1473V33 and CY7C1475V33 are  
3.3V, 2M x 36/4M x 18/1M x 72 synchronous flow through burst  
SRAMs designed specifically to support unlimited true  
back-to-back read or write operations without the insertion of  
wait states. The CY7C1471V33, CY7C1473V33 and  
CY7C1475V33 are equipped with the advanced No Bus  
Latency (NoBL) logic required to enable consecutive read or  
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.  
• Supportsupto133MHzbusoperationswithzerowaitstates  
• Data is transferred on every clock  
• PincompatibleandfunctionallyequivalenttoZBT™devices  
• 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 IO supply (VDDQ  
)
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).  
• Fast clock-to-output times  
— 6.5 ns (for 133-MHz device)  
• Clock Enable (CEN) pin to enable clock and suspend  
operation  
• Synchronous self timed writes  
Write operations are controlled by 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.  
• Asynchronous Output Enable (OE)  
• CY7C1471V33, CY7C1473V33 available in  
JEDEC-standard Pb-free 100-Pin TQFP, Pb-free and  
non-Pb-free 165-Ball FBGA package. CY7C1475V33  
available in Pb-free and non-Pb-free 209-Ball FBGA  
package  
Three synchronous Chip Enables (CE1, CE2, CE3) and an  
asynchronous Output Enable (OE) provide for easy bank  
selection and output tri-state control. To avoid bus contention,  
the output drivers are synchronously tri-stated during the data  
portion of a write sequence.  
• Three Chip Enables (CE1, CE2, CE3) for simple depth  
expansion  
• Automatic power down feature available using ZZ mode or  
CE deselect  
• IEEE 1149.1 JTAG Boundary Scan compatible  
• Burst Capability — linear or interleaved burst order  
• Low standby power
