Static Random Access Memory  
DESCRIPTION  
The Accutek AK63264W-72 SRAM Module consists of fast high  
performance SRAMs mounted on a low profile, 72 pin SIM Board.  
The module utilizes four 28 pin 64K x 4 SRAMs in SOJ packages  
and four decoupling capacitors mounted on each side of a printed  
circuit board.  
Front View  
72-Pin SIM  
The SRAMs used have common I/O functions and single output en-  
able functions. Also, four separate chip select (CE) connections are  
used to independently enable the four bytes. The modules can be  
supplied in a variety of access time values from 12 nSEC to  
45 nSEC in CMOS or BiCMOS technology.

The Accutek module is designed to have a maximum seated height  
of 0.600 inch to provide for the lowest height off the board. By off-  
set-mounting the back surface SRAMs the module can be mounted  
in either angled or straight-up SIM sockets. The module conforms  
to JEDEC standard sizes and pin-out configurations. Using two  
pins for module memory density identification, PD0 and PD1, mini-  
mizes interchangeability and design considerations when changing  
from one module size to another in customer applications.  
· Downward compatible with 128K x 32 (AK632128) and  
32K x 32 (AK63232)  
· Presence Detect PD0 and PD1 for identifying module density  
· Fast access times range from 12 nSEC BiCMOS to 45 nSEC  
CMOS  
· TTL-compatible inputs and outputs  
· Single +5 Volt ( 10ꢀ) power supply  
· Operating temperature range in free air, 00C to 700C  
· Available with solder or gold leads  
FEATURES  
· 65,536 x 32 bit organization  
· JEDEC Standardized 72 pin SIM or ZIP pinout  
· Common I/O, single OE functions with four separate chip  
selects (CE)  
ELECTRICAL SPECIFICATIONS  
Timing diagrams and basic electrical characteristics are those of the  
standard 64K x 4 SRAMs used to construct these modules. Accutek’s  
module design allows the flexibility of selecting industry-compatible  
64K x 4 SRAMs from several semiconductor manufacturers.  
· Low height, 0.600 inch maximum  
· Upward compatible with 256K x 32 (AK632256) 512K x 32  
(AK632512) and 1 Meg x 32 (AK6321024)
