AK68512D1C  
524,288 x 8 Bit CMOS  
Static Random Access Memory  
ACCUTEK  
MICROCIRCUIT CORPORATION  
DESCRIPTION  
The Accutek AK68512D1C high density memory module is a static  
random access memory organized in 512K x 8 bit words. The as-  
sembly consists of one medium speed 512K x 8 SRAM in a TSOP  
Type 2 package. The module is supplied in a 600 mil wide, 32 pin  
DIP (Dual In-Line Package) configuration. This pinout is completely  
compatible with industry standard monolithic designs. These mod-  
ules are intended for use in applications where limited board space  
dictates compact module designs.  
The operation of the AK68512D1C is identical to standard mono-  
lithic 8 bit word wide SRAMs.  
The AK68512D1C offers the features of low power and medium  
speed by using CMOS devices and makes high density mounting  
possible with no surface mount technology.  
FEATURES  
· 524,288 x 8 bit organization  
ELECTRICAL SPECIFICATIONS  
· Fast access time: 55 - 70 nSEC  
Timing diagrams and basic electrical characteristics are those of  
the standard 512K x 8 SRAMs used to construct these modules.  
Accutek’s module design allows the flexibility of selecting indus-  
try-compatible 512K x 8 SRAMs from any of a number of semicon-  
ductor manufacturers.  
· Completely static RAM, no clock or timing strobe required  
· Inputs and outputs TTL compatible  
· Conventional 600 mil wide SIP package with industry  
compatible pinout  
· Single 5 volt power supply - AK68512D1C  
· Single 3.3 volt power supply - AK68512D1C/3.3  
· Operating free air temperature 00 to 700C
