DESCRIPTION
The SCE5780 (red), SCE5781 (yellow), SCE5782 (HER), SCE5783
(green), SCE5784 (HEG), SCE5785 (orange), and SCE5786 (InGaAlP
red) are eight digit, dot addressable 5x7 dot matrix, serial input, Intelli-
gent Display devices. The eight 0.180" (4.57 mm) high digits are pack-
aged in a rugged, high quality, optically transparent, plastic 26 pin DIP
with 0.3" pin spacing.
The on-board CMOS has a 280 bit RAM, one bit associated with one
LED, each to generate User Dened Characters.
The SCE578X is designed to work with the serial port of most com-
mon microprocessors. Data is transferred into the display through the
Serial Data Input (DATA), clocked by the Serial Data Clock (SDCLK),
and enabled by the Load Input (LOAD).
