AK632512AW - 64 Pin Version  
524,288 x 32 Bit CMOS / BiCMOS  
Static Random Access Memory  
DESCRIPTION  
Front View  
The Accutek AK632512AW SRAM Module consists of fast high per-  
formance SRAMs mounted on a low height, 64 pin SIM Board. The  
module utilizes four 36 pin 512K x 8 SRAMs in 400 mil SOJ pack-  
ages and four decoupling capacitors mounted two on the front side  
and two on the back side of a printed circuit board.

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 15 nSEC to  
35 nSEC in CMOS or BiCMOS technology.  
Back View  
The Accutek module is designed to have a maximum seated height  
of 0.640 inch SIM to provide for the lowest height off the board. The  
module conforms to JEDEC-standard size. The Presence Detect  
feature has been disabled on this 64 pin module. The customer  
must jumper his board to provide density identification. The avail-  
able 72 pin module has the Presence Detect feature operational.

replaces PD1 on Pin #3  
· Upward compatible with 1 Meg x 32 (AK6321024)  
· TTL-compatible inputs and outputs  
· Common I/O, single OE and WE functions with four separate  
chip selects (CE)  
· Single +5 Volt (æ10%) power supply  
· Operating free air temperature 00 to 700C  
· Fast access times from 15 nSEC  
· Low height, 0.640 inch SIM maximum

ELECTRICAL SPECIFICATIONS  
720mA Max Active (20 nSEC)  
760mA Max Active (15 nSEC)  
800mA Max Active (12 nSEC)  
200mA Max Standby  
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 several SRAM manufacturers.
