DESCRIPTION
The Accutek AK631024 SRAM Module consists of fast high perfor-
mance SRAMs mounted on a low profile, 72 pin SIM or ZIP PCB.
The module utilizes four 32 pin 1 Meg x 4 SRAMs in 400 mil SOJ
packages and four decoupling capacitor chips 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
suppliedinavarietyofaccesstimevaluesfrom15nSECto30nSEC
in CMOS or BiCMOS technology.
The Accutek module is designed to have a maximum seated height
of 0.670 inch SIM or 0.550 inch ZIP to provide for the lowest height
offtheboard. EachconformstoJEDEC-standardsizesandpin-out
