CY7C1364B  
9-Mb (256K x 32) Pipelined Sync SRAM  
Features  
Functional Description[1]  
• Registered inputs and outputs for pipelined operation  
• 256K × 32 common I/O architecture  
• 3.3V core power supply  
• 3.3V I/O operation  
• Fast clock-to-output times  
The CY7C1364B SRAM integrates 262,144 x 32 SRAM cells  
with advanced synchronous peripheral circuitry and a two-bit  
counter for internal burst operation. All synchronous inputs are  
gated by registers controlled by a positive-edge-triggered  
Clock Input (CLK). The synchronous inputs include all  
addresses, all data inputs, address-pipelining Chip Enable  
(
), depth-expansion Chip Enables (CE and  
), Burst

inputs include the Output Enable ( ) and the ZZ pin.  
OE  
• Provide high-performance 3-1-1-1 access rate  
Addresses and chip enables are registered at rising edge of  
• User-selectable burst counter supporting Intel  
clock when either Address Strobe Processor (  
) or  
ADSP  
Pentium® interleaved or linear burst sequences  
Address Strobe Controller (  
) are active. Subsequent  
ADSC  
burst addresses can be internally generated as controlled by  
the Advance pin ( ).  
• 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  
ADV  
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 four bytes wide as  
controlled by the Byte Write control inputs.  
when active  
GW  
causes all bytes to be written.  
LOW  
The CY7C1364B 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.
