DESCRIPTION

The SCD55100A (Red), SCD55101A (Yellow),

SCD55102A (HER), SCD55103A (Green) and

SCD55104A (HEG) are eight digit dot addressable 5 x 5

matrix, Serial Input, Intelligent Display devices.

The ten 3.68 mm (0.145") high digits are packaged in a

rugged, high quality optically transparent, standard

7.62

mm (0.3") pin spacing 28 pin plastic DIP.

The on-board CMOS has a 250 bit RAM, one bit associ-

ated with one LED, each to generate User Defined Char-

acters. Due to the reduced LED count, power

requirement and heat dissipation are reduced by 30%.

Additionally in Power Down Mode quiescent current

<50 µA.

The SCD5510XA is designed to work with the Serial port

of most common microprocessors. The multiplex Clock

I/O (CLK I/O) and multiplex Clock Select (

CLKSEL) pins

offer the user the capability to supply a high speed

external multiplex clock. This feature can minimize audio

in-band interference for portable communication

equipment or eliminate the visual synchronization effects

found in high vibration environments such as avionics

equipment.

SCD55100A, SCD55101A, SCD55102A, SCD55103A, SCD55104A The following explains how to format the serial data to be loaded into the display. The user supplies a string of bit mapped decoded characters. The contents of this string is shown in Figure „Loading Serial Character Data a“ (page 8). Figure „Loading Serial Character Data b“ (page 8) shows that each character consist of six 8 bit words. The first word encodes the display character location and the succeeding five bytes are row data.

Naturally, 28 pin DIP sockets 7.62 mm (0.300") wide with 2.54 mm (0.100") centers work well for single displays. Multiple display assemblies are best handled by longer SIP sockets or DIP sockets when available for uniform package alignment. Socket manufacturers are Aries Electronics, Inc.

SCD55100A, SCD55101A, SCD55102A, SCD55103A, SCD55104A Additional contrast enhancement is gained by shading the displays. Plastic band-pass filters with built-in louvers offer the next step up in contrast improvement. Plastic filters can be improved further with anti-reflective coatings to reduce glare. The trade-off is fuzzy characters. Mounting the filters close to the display reduces this effect. Take care not to overheat the plastic filter by allowing for proper air flow.
