AND1021ST/-EO
120 x 64 Dots
Intelligent Graphics Display
The AND1021ST/-EO devices are compact, full dot matrix,
LCD modules that have an on-board LCD controller
(T6963C) and display memory (RAM). The AND1021ST/-EO
can display TEXT information, numerals, letters and
symbols, as well as GRAPHIC patterns. These devices are
suitable for medical and measurement equipment, point-of-
sale terminals, portable equipment, and marine
instrumentation.

Because signal lines are directly connected
to C-MOS and are not pull-up or pull-down
internally, except RESET which is pull-up to
V
DD
, you must guard all signals from
external noise.
