STATIC RAM  
FEATURES  
DESCRIPTION  
The ISSI IS65C256 is a low power, 32,768 word by 8-bit  
CMOS static RAM. It is fabricated using ISSI's high-  
performance, low power CMOS technology.  
• High-speed access time: 20 ns  
Low active power: 200 mW (typical)  
Low standby power:  
When CS is HIGH (deselected), the device assumes a  
standby mode at which the power dissipation can be  
reduced down to 250 µW (typical) at CMOS input levels.  
250 µW (typical) CMOS standby  
• Fully static operation: no clock or refresh  
required  
Easy memory expansion is provided by using an active  
LOW Chip Select (CS) input and an active LOW Output  
Enable (OE) input. The active LOW Write Enable (WE)  
controls both writing and reading of the memory.  
• TTL compatible inputs and outputs  
• Single 5V power supply  
• Temperature Offerings:  
Option A1: –40oC to +85oC  
Option A2: –40oC to +105oC  
Option A3: –40oC to +125oC
