28A  
CY7C128A  
2K x 8 Static RAM  
provided by an active LOW Chip Enable (CE), and active LOW  
Output Enable (OE) and three-state drivers. The CY7C128A  
has an automatic power-down feature, reducing the power  
consumption by 83% when deselected.  
Features  
• Automatic power-down when deselected  
• CMOS for optimum speed/power  
• High speed  
Writing to the device is accomplished when the Chip Enable  
(CE) and Write Enable (WE) inputs are both LOW.  
— 15 ns  
Data on the eight I/O pins (I/O0 through I/O7) is written into the  
memory location specified on the address pins (A0 through  
A10).  
• Low active power  
— 660 mW (commercial)  
— 688 mW (military—20 ns)  
• Low standby power  
Reading the device is accomplished by taking Chip Enable  
(CE) and Output Enable (OE) LOW while Write Enable (WE)  
remains HIGH. Under these conditions, the contents of the  
memory location specified on the address pins will appear on  
the eight I/O pins.  
— 110 mW (20 ns)  
• TTL-compatible inputs and outputs  
• Capable of withstanding greater than 2001V electro-  
static discharge  
The I/O pins remain in high-impedance state when Chip En-  
able (CE) or Output Enable (OE) is HIGH or Write Enable (WE)  
is LOW.  
• VIH of 2.2V  
Functional Description  
The CY7C128A utilizes a die coat to insure alpha immunity.  
The CY7C128A is a high-performance CMOS static RAM or-  
ganized as 2048 words by 8 bits. Easy memory expansion is
