These components are assembled in a compact plastic package. Individual LED dot addressablity allows the user great freedom in creating special characters or mini-icons. The User Definable Character Set examples illustrate 200 different character and sym- bol possibilities. Each example has the hexadecimal code required to display characters in a horizontal or vertical format. See Figures above, Suggested Display Mounting, for the display positioning. Generally, the contacts should be on the right side of the display for the vertical format and on the top of the display for the horizon- tal format. Character Address, Row, & Column Data Map 1. Viewed from the LED side of the display with the display in a horizontal position. 2. The row address and column data are typical for all character posi- tions. The LED is on when the data bit = 1 and off when the data bit = 0. Suggested Display Mounting 90° SIP Connector / Header Packages The serial data interface provides a highly efficient interconnection between the display and the mother board. The SCDQ554XX requires only three input lines as compared to 15 for an equivalent four character parallel input part. The on-board CMOS IC is the electronic heart of the display. The IC accepts decoded serial data, which is stored in the internal RAM. Asynchronously the RAM is read by the character multi- plexer at a strobe rate that results in a flicker free display. shows the three functional areas of the IC. These include: the input serial data register and control logic, a 100 bits two port RAM, and an internal multiplexer/display driver.
