ACCUTEK
MICROCIRCUIT CORPORATION
DESCRIPTION
The Accutek AK68128D1C high density memory module is a static
random access memory organized in 128K x 8 bit words. The as-
sembly consists of one medium speed 128K x 8 SRAM in a TSOP
Type 1 package. The module is supplied in a 600 mil wide, 32 pin
DIP (Dual In-Line Package) configuration. This pinout is completely
compatible with industry standard monolithic designs. These mod-
ules are intended for use in applications where limited board space
dictates compact module designs.
The operation of the AK68182D1C is identical to standard mono-
lithic 8 bit word wide SRAMs.
The AK68128D1C offers the features of low power and medium
speed by using CMOS devices and makes high density mounting
possible with no surface mount technology.
