CY7C1471BV25  
CY7C1473BV25, CY7C1475BV25  
72-Mbit (2M x 36/4M x 18/1M x 72)  
Flow-Through SRAM with NoBL™ Architecture  
Features  
Functional Description  
■ No Bus Latency™ (NoBL™) architecture eliminates dead  
cycles between write and read cycles  
The CY7C1471BV25, CY7C1473BV25, and CY7C1475BV25  
are 2.5V, 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 CY7C1471BV25, CY7C1473BV25, and  
CY7C1475BV25 are equipped with the advanced No Bus  
Latency (NoBL) logic required to enable consecutive read or  
write operations with data 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.  
■ Supports up to 133 MHz bus operations with zero wait states  
■ Data transfers on every clock  
■ Pin compatible and functionally equivalent to ZBT™ devices  
■ Internally self timed output buffer control to eliminate the need  
to use OE  
■ Registered inputs for flow through operation  
■ Byte Write capability  
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).  
■ 2.5V IO supply (VDDQ  
)
■ Fast clock-to-output times  
❐ 6.5 ns (for 133-MHz device)  
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.  
■ Clock Enable (CEN) pin to enable clock and suspend operation  
■ Synchronous self timed writes  
Three synchronous Chip Enables (CE1, CE2, CE3) and an  
asynchronous Output Enable (OE) provide 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.  
■ Asynchronous Output Enable (OE)  
■ CY7C1471BV25, CY7C1473BV25 available in  
JEDEC-standard Pb-free 100-pin TQFP, Pb-free and  
non-Pb-free 165-ball FBGA package. CY7C1475BV25  
available in Pb-free and non-Pb-free 209-ball FBGA package.  
For best practice recommendations, refer to the Cypress appli-  
cation note AN1064, SRAM System Guidelines.  
■ 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
