Description
The HCMS-29xx series are high
performance, easy to use dot
matrix displays driven by on-board
CMOS ICs. Each display can be
directly interfaced with a
microprocessor, thus eliminating
the need for cumbersome interface
components. The serial IC
interface allows higher character
count information displays with a
minimum of data lines. A variety of
colors, font heights, and character
counts gives designers a wide
range of product choices for their
specific applications and the easy
to read 5 x 7 pixel format allows
the display of uppercase, lower
case, Katakana, and custom user-
defined characters. These displays
are stackable in the x- and y-
directions, making them ideal for
high character count displays.
