CY7C186  
8Kx8 Static RAM  
provided by an active LOW chip enable (CE1), an active HIGH  
chip enable (CE2), and active LOW output enable (OE) and  
three-state drivers. The device has an automatic power-down  
feature (CE1), reducing the power consumption by over 80%  
when deselected. The CY7C186 is in a 600-mil-wide PDIP  
package and a 32-pin TSOP (std. pinout).  
Features  
• High speed  
— 20 ns  
• Low active power  
An active LOW write enable signal (WE) controls the writ-  
ing/reading operation of the memory. When CE1 and WE in-  
puts are both LOW and CE2 is HIGH, data on the eight data  
input/output pins (I/O0 through I/O7) 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 ad-  
dressed by the information on address pins are present on the  
eight data input/output pins.  
— 605 mW  
• Low standby power  
— 110 mW  
• CMOS for optimum speed/power  
• Easy memory expansion with CE1, CE2, and OE  
features  
• TTL-compatible inputs and outputs  
• Automatic power-down when deselected  
The input/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.  
Functional Description  
The CY7C186 is a high-performance CMOS static RAM orga-  
nized as 8192 words by 8 bits. Easy memory expansion is
