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 eight 28 pin 64K x 4 SRAMs in SOJ packages
and four decoupling capacitors mounted on each 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 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, PD
