IS61C256AL  
32K x 8 HIGH-SPEED CMOS STATIC RAM  
MAY 2012  
DESCRIPTION  
FEATURES  
The ISSI IS61C256AL is a very high-speed, low power,  
32,768 word by 8-bit static RAMs. It is fabricated using  
ISSI's high-performance CMOS technology. This highly  
reliable process coupled with innovative circuit design  
techniques,yieldsaccesstimesasfastas10nsmaximum.  
• High-speed access time: 10, 12 ns  
• CMOS Low Power Operation  
— 1 mW (typical) CMOS standby  
— 125 mW (typical) operating  
• Fully static operation: no clock or refresh  
required  
When CE is HIGH (deselected), the device assumes a  
standby mode at which the power dissipation can be  
reduced down to 150 µW (typical) with CMOS input levels.  
• TTL compatible inputs and outputs  
• Single 5V power supply  
• Lead-free available  
Easy memory expansion is provided by using an active  
LOW Chip Enable (CE) input and an active LOW Output  
Enable (OE) input. The active LOW Write Enable (WE)  
controls both writing and reading of the memory.  
TheIS61C256ALispincompatiblewithother32Kx8SRAMs  
and are available in 28-pin SOJ and TSOP (Type I)  
packages.
