CY7C185  
64-Kbit (8K x 8) Static RAM  
Features  
Functional Description  
High speed  
15 ns  
The CY7C185[1] is a high-performance CMOS static RAM  
organized as 8192 words by 8 bits. Easy memory expansion is  
provided by an active LOW chip enable (CE1), an active HIGH  
chip enable (CE2), and active LOW output enable (OE) and  
tri-state drivers. This device has an automatic power down  
feature (CE1 or CE2), reducing the power consumption by 70%  
when deselected. The CY7C185 is in a standard 300-mil-wide  
DIP, SOJ, or SOIC package.  
Fast tDOE  
Low active power  
715 mW  
Low standby power  
85 mW  
An active LOW write enable signal (WE) controls the  
writing/reading operation of the memory. When CE1 and WE  
inputs are both LOW and CE2 is HIGH, data on the eight data  
input/output pins (IO0 through IO7) is written into the memory  
location addressed by the address present on the address pins  
(A0 through A12). Reading the device is accomplished by  
selecting the device and enabling the outputs, CE1 and OE  
active LOW, CE2 active HIGH, while WE remains inactive or  
HIGH. Under these conditions, the contents of the location  
addressed by the information on address pins are present on the  
eight data input or output pins.  
CMOS for optimum speed/power  
Easy memory expansion with CE1, CE2 and OE features  
TTL-compatible inputs and outputs  
Automatic power down when deselected  
Available in non Pb-free 28-pin (300-Mil) Molded SOJ, 28-pin  
(300-Mil) Molded SOIC and Pb-free 28-pin (300-Mil) Molded  
DIP  
The input or output pins remain in a high-impedance state unless  
the chip is selected, outputs are enabled, and write enable (WE)  
is HIGH. A die coat is used to insure alpha immunity.
