CY7C128A  
2K x 8 Static RAM  
Features  
Functional Description  
• Automatic power-down when deselected  
• CMOS for optimum speed/power  
• High speed  
The CY7C128A is a high-performance CMOS static RAM  
organized as 2048 words by 8 bits. Easy memory expansion  
is provided by an active LOW Chip Enable (CE), and active  
LOW Output Enable (OE) and tri-state drivers. The CY7C128A  
has an automatic power-down feature, reducing the power  
consumption by 83% when deselected.  
— 15 ns  
• Low active power  
Writing to the device is accomplished when the Chip Enable  
(CE) and Write Enable (WE) inputs are both LOW.  
— 660 mW (commercial)  
• Low standby power  
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  
— 110 mW (20 ns)  
A10).  
• TTL-compatible inputs and outputs  
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.  
• Capable of withstanding greater than 2001V electro-  
static discharge  
• Available in Pb-free and non Pb-free 24-pin Molded  
SOJ, non Pb-free 24-pin (300-Mil) Molded DIP  
The I/O pins remain in high-impedance state when Chip  
Enable (CE) or Output Enable (OE) is HIGH or Write Enable  
(WE) is LOW.  
The CY7C128A utilizes a die coat to insure alpha immunity.
