AK68512D  
524,288 x 8 Bit CMOS  
Static Random Access Memory  
DESCRIPTION  
The Accutek AK68512D high density memory module is a static  
random access memory organized in 512K x 8 bit words. The as-  
sembly consists of two medium speed 128K x 8 SRAMs in thin  
TSOP packages and a CMOS decoder logic IC mounted on the top  
side and two medium speed 128K x 8 SRAMs in thin TSOP pack-  
ages mounted on the bottom surfaces of a printed circuit board.  
The module is supplied in a 600 mil wide,32 pin DIP (Dual In-Line  
Package) configuration. This pinout is completely compatible with  
forthcoming industry standard monolithic designs. These modules  
are intended for use in applications where limited board space dic-  
tates compact module designs.  
The operation of the AK68512D is identical to standard monolithic 8  
bit word wide SRAMs.  
The AK68512D 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  
ELECTRICAL SPECIFICATIONS  
· 524,288 x 8 bit organization  
Timing diagrams and basic electrical characteristics are those of  
the standard 128K x 8 SRAMs used to construct these modules.  
Accutek’s module design allows the flexibility of selecting indus-  
try-compatible 128K x 8 SRAMs from any of a number of semicon-  
ductor manufacturers.  
· Fast access time: 85 - 120 nSEC  
· 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 (+/- 10%) power supply  
· Operating free air temperature 00 to 700C
