DESCRIPTION
The Accutek AK632128 SRAM Module consists of fast high perfor-
mance SRAMs mounted on a low height, 64 pin SIM or ZIP PCB.
The module utilizes four 32 pin 128K x 8 SRAMs in 400 mil SOJ
packagesandfourdecouplingcapacitorsmountedonthefrontside
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 7nSEC to 35nSEC
in CMOS or BiCMOS technology.
The Accutek module is designed to have a maximum seated height
of 0.620 inch SIM or 0.540 inch ZIP to provide for the lowest height
offtheboard. EachconformstoJEDEC-standardsizesandpin-out
configurations. Using two pins for module denisty identification,

ations when changing from one module size to the other in cus-
tomer applications.
