CY7C1325F  
4-Mb (256K x 18) Flow-Through Sync SRAM  
minimum glue logic. Maximum access delay from clock rise is  
6.5 ns (133-MHz version). A 2-bit on-chip counter captures the  
first address in a burst and increments the address automati-

are gated by registers controlled by a positive-edge-triggered  
Clock Input (CLK). The synchronous inputs include all

The CY7C1325F allows either interleaved or linear burst  
sequences, selected by the MODE input pin. A HIGH selects  
an interleaved burst sequence, while a LOW selects a linear  
burst sequence. Burst accesses can be initiated with the  
Processor Address Strobe (ADSP) or the cache Controller  
Address Strobe (ADSC) inputs.  
• Provide high-performance 2-1-1-1 access rate  
• User-selectable burst counter supporting Intel

• Separate processor and controller address strobes  
• Synchronous self-timed write  
Addresses and chip enables are registered at rising edge of  
clock when either Address Strobe Processor (

• Asynchronous output enable  
Address Strobe Controller (

The CY7C1325F operates from a +3.3V core power supply  
while all outputs may operate with either a +2.5 or +3.3V  
supply. All inputs and outputs are JEDEC-standard  
JESD8-5-compatible.  
• “ZZ” Sleep Mode option
