DESCRIPTION
The Accutek family of AccuZIP DRAM adapter modules is designed
to convert a DRAM in a surface mount SOJ package into a
side-mounted ZIP package. This pin compatible module eliminates
PC board retooling when monolithic ZIP packages become unavail-
able. These AccuZIP modules can be used to save space on com-
plex circuit boards using thru-hole technology.
The family consists of a series of unique low-profile printed circuit
boards designed to accept IC’s in either 0.300" SOJ packages for
the 256K x 4, 1 MEG x 4, 1 MEG x 1 and 4 MEG x 1 or 0.400" SOJ
packages for the 512K x 8, 256K x 16, 256K x 18, 1 MEG x 16 and 1
MEG x 18.
FEATURES
· Saves costly redesign of current PC boards
· Allows for increased memory and density
· On board decoupling capacitor
· Low height of 0.425" above mother board
· 100% tested with life time warranty
