CY7C1354CV25  
CY7C1356CV25  
PRELIMINARY  
9-Mbit (256K x 36/512K x 18) Pipelined SRAM  
with NoBL™ Architecture  
Features  
Functional Description  
• Pin-compatible with and functionally equivalent to  
ZBT™  
The CY7C1354CV25 and CY7C1356CV25 are 2.5V, 256K x  
36 and 512K x 18 Synchronous pipelined burst SRAMs with  
No Bus Latency™ (NoBL™) logic, respectively. They are  
designed to support unlimited true back-to-back Read/Write  
operations with no wait states. The CY7C1354CV25 and  
CY7C1356CV25 are equipped with the advanced (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 in systems that  
require frequent Write/Read transitions. The CY7C1354CV25  
and CY7C1356CV25 are pin-compatible with and functionally  
equivalent to ZBT devices.  
• Supports 225-MHz bus operations with zero wait states  
— Available speed grades are 225, 200, and 167 MHz  
• Internally self-timed output buffer control to eliminate  
the need to use asynchronous OE  
• Fully registered (inputs and outputs) for pipelined  
operation  
• Byte Write capability  
• Single 2.5V power supply  
All synchronous inputs pass through input registers controlled  
by the rising edge of the clock. All data outputs pass through  
output 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.  
• Fast clock-to-output times  
— 2.8 ns (for 225-MHz device)  
— 3.2ns (for 200-MHz device)  
— 3.5 ns (for 167-MHz device)  
• Clock Enable (CEN) pin to suspend operation  
• Synchronous self-timed writes  
Write operations are controlled by the Byte Write Selects  
(BWa–BWd for CY7C1354CV25 and BWa–BWb for  
CY7C1356CV25) and a Write Enable (WE) input. All writes are  
conducted with on-chip synchronous self-timed write circuitry.  
• Available in lead-free 100 TQFP, 119 BGA, and 165 fBGA  
packages  
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.  
• IEEE 1149.1 JTAG Boundary Scan  
• Burst capability–linear or interleaved burst order  
• “ZZ” Sleep Mode option and Stop Clock option
