The SCDV5540 (Red), SCDV5541 (Yellow), SCDV5542 (High Efficiency Red), SCDV5543 (Green), and SCDV5544 (High Efficiency Green) are four digit, dot addressable 5x5 dot matrix, serial input, alphanumeric Intelligent Display devices in a vertical format. The four digits are packaged in a rugged, high quality, optically transparent, plastic 14 pin DIP with 0.3" pin spacing.
The on-board CMOS SCDV5544 has a 100 bit RAM, one bit associated with one LED, each to generate User Defined Characters. In Power Down Mode, quiescent current is <50mA.
The SCDV5544 is designed for work with the serial port of most common 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).
The Clock I/O (CLK I/O) and Clock Select (CLK SEL) pins offer the user
the capability to supply a high speed external multiplex clock. This SCDV5544 feature can minimize audio in-band interference for portable communication equipment or eliminate the visual sychronization effects found in high vibration environments such as avionic equipment
