HDSP-2131, HDSP-2132, HDSP-2133, HDSP-2179
Eight Character 5.0 mm (0.2 inch) Glass/Ceramic
Intelligent 5x7 Alphanumeric Displays
for Military Applications
Data Sheet
Description
The HDSP-2131 (yellow), HDSP-2179 (orange),
HDSP-2132 (high efficiency red) and the HDSP-2133
(green) are eight-digit, 5 x 7 dot matrix, alphanu-
meric displays. The 5.0 mm (0.2 inch) high characters
are packaged in a standard 7.64 mm (0.30 inch) 32
pin DIP. The on-board CMOS IC has the ability to
decode 128 ASCII characters, which are permanently
stored in ROM. In addition, 16 programmable
symbols may be stored in an on-board RAM. Seven
brightness levels provide versatility in adjusting the
display intensity and power consumption. The
HDSP-213x and HDSP-2179 are designed for stan-
dard microprocessor interface techniques. The
display and special features are accessed through a
bidirectional eight-bit data bus. These features
make the HDSP-213x and HDSP-2179 ideally suited
for applications where a hermetic, low power alpha-
numeric display is required.
