Static Random Access Memory  
DESCRIPTION  
The Accutek AK681024G is a high density SRAM memory module  
organized in 1 Meg X 8 bit words. The assembly consists of four me-  
dium speed 128K X 8 SRAMs in thin TSOP packages, plus a CMOS  
decoder logic IC and four decoupling capacitor chips, mounted on  
the front side and four medium speed 128K x 8 SRAMS in thin  
TSOP packages and four decoupling capacitor chips mounted on  
the back side of a low-profile printed circuit board. The module con-  
figuration is a 36 pin leaded SIP.

The memory operates as a single asynchronous 1 Meg X 8 SRAM  
from a 5V supply, and has common I/O, chip enable, output enable  
and write enable functions. With the proper choice of SRAMs, it is  
available in three separate low-standby-power configurations, with  
access times of 55, 70, 85 or 100 nSEC.  
The combination of low power, low profile and high density packag-  
ing offered by the AK681024G makes it ideal for use in applications  
where board space and available power are limited and extremely  
low access times are not required. It is especially useful in VMEbus  
designs and in places where very close module-to-module spacing  
is dictated.  
· Range of access times from 55 to 100 nSEC  
· Low, low-low and ultra-low standby power level versions avail-  
able  
· Single 5 volt power supply - AK681024G  
FEATURES  
· Single 3.3 volt power supply - AK681024G/3.3  
· Operating free air temerature 00C to 700C (Industrial range  
· 1,048,576 x 8 bit organization  
version of -100C to 850C also available)  
· JEDEC Standard 36 pin SIP format  
· Common I/O, single OE, CE and WE functions  
· Completely static and asynchronous, no clock or timing strobe  
required  
· Low 0.550 inch maximum seated height and thin profile allow  
maximum board density
