DESCRIPTION
TheAccutekAK632512AWSRAMModuleconsistsoffasthighper-
formanceSRAMsmountedonalowheight,64pinSIM 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.
TheSRAMsusedhavecommonI/Ofunctionsandsingleoutputen-
ablefunctions. Also,fourseparatechipselect(CE)connectionsare
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.
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.
