The PDSP1880 (Red), PDSP1881 (Yellow), PDSP1882
(High Efficiency Red), PDSP1883 (Green), and
PDSP1884 (High Efficiency Green) are eight digit,
5 x 7 dot matrix, alphanumeric Programmable Displays.
The 4.70 mm (0.180’’) high digits are packaged in a rug-
ged, high quality, optically transparent, 7.62 mm (0.300’’)
lead spacing, 30 pin plastic DIP.
The on-board CMOS has a built-in 128 character ROM.
The PDSP188X also has a user definable character
(UDC) feature, which uses a RAM that permits storage of
16 arbitrary characters, symbols or icons that are soft-
ware-definable by the user. The character ROM itself is
mask programmable and easily modified by the manufac-
turer to provide specified custom characters.
The PDSP188X is designed for standard microprocessor
interface techniques, and is fully TTL compatible. The
Clock I/O and Clock Select pins allow the user to cas-
cade multiple display modules.
ESD Warning:
Standard precautions for
CMOS handling should be
observed.
