Description
The HDSP-210X/-211X/-250X
series of products is ideal for
applications where displaying
eight or more characters of dot
matrix information in an
aesthetically pleasing manner is
required. These devices are
8-digit, 5 x 7 dot matrix, alpha-
numeric displays and are all
packaged in a standard 15.24 mm
(0.6 inch) 28 pin DIP. The on-
board CMOS IC has the ability to
decode 128 ASCII characters
which are permanently stored in
ROM. In addition, 16 program-
mable symbols may be stored in
on-board ROM, allowing consider-

HDSP-250X Series
able flexibility for displaying
additional symbols and icons.
Seven brightness levels provide
versatility in adjusting the display
intensity and power consumption.
The HDSP-210X/-211X/-250X
products are designed for
standard microprocessor interface
techniques. The display and
special features are accessed
through a bidirectional 8-bit data
bus.
