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, alphanumeric
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 ad-
justing the display intensity and
power consumption. The HDSP-
213X is designed for standard
microprocessor interface tech-
niques. The display and special
features are accessed through a
bidirectional eight-bit data bus.
These features make the HDSP-
213X ideally suited for applica-
tions where a hermetic, low
power alphanumeric display is
required.
