DESCRIPTION
The Accutek AK63216Z SRAM Module consists of fast high perfor-
mance SRAMs mounted on a low profile, 64 pin ZIP Board. The
moduleutilizesfour28pin32Kx8SRAMsin300milSOJpackages
and four decoupling capacitors mounted on the front side of a
printed circuit board. Eliminating Pin 30 makes a 16K x 32 bit mod-
ule using four 32K x 8 SRAMs.
TheSRAMsusedhavecommonI/Ofunctionsandsingleoutputen-
ablefunctions. Also,fourseparatechipselect(CE)connectionsare
used to independently enable the four bytes. The modules can be
suppliedinavarietyofaccesstimevaluesfrom8nSECto45nSEC
in CMOS or BiCMOS technology.
The Accutek module is designed to have a maximum seated height
of 0.500 inch. The module conforms to JEDEC-standard sizes and
pin-out configurations. This, along with use of two pins for module
memory density identification, PD
0
and PD
1
, minimizes
interchangeability and design considerations when changing from
one module size to the other in customer applications.
