CY7C1326F  
2-Mb (128K x 18) Pipelined Sync SRAM  
counter for internal burst operation. All synchronous inputs are  
gated by registers controlled by a positive-edge-triggered  
Features  
• Registered inputs and outputs for pipelined operation  
• 128K × 18 common I/O architecture  
• 3.3V core power supply  
• 3.3V I/O operation  
• Fast clock-to-output times

clock when either Address Strobe Processor (  
) or  
ADSP  
Address Strobe Controller (  
) are active. Subsequent  
ADSC  
burst addresses can be internally generated as controlled by  
the Advance pin ( ).  
• Provide high-performance 3-1-1-1 access rate  
ADV  
• User-selectable burst counter supporting Intel  
Address, data inputs, and write controls are registered on-chip  
to initiate a self-timed Write cycle.This part supports Byte Write  
operations (see Pin Descriptions and Truth Table for further  
details). Write cycles can be one to two bytes wide as  
Pentium® interleaved or linear burst sequences  
• Separate processor and controller address strobes  
• Synchronous self-timed writes  
• Asynchronous output enable  
• Offered in JEDEC-standard 100-pin TQFP package  
• “ZZ” Sleep Mode Option

The CY7C1326F operates from a +3.3V core power supply  
while all outputs also operate with a +3.3V supply. All inputs  
and outputs are JEDEC-standard JESD8-5-compatible.  
The CY7C1326F SRAM integrates 131,072 x18 SRAM cells  
with advanced synchronous peripheral circuitry and a two-bit
