Only one external resistor is required to set the current through the LED display. Brightness can be controlled either in an analog or digital way. The user can choose the internal code-B decoder to display numeric digits or to address each segment directly. The AS1100 features an extremely low shutdown current of only 20µA. and an operational current of less than 500µA. The number of visible digits can be programmed as well. The AS1100 can be reset by software and an external clock can be used. Several test modes support easy debugging. The AS1100 is fully compatible to the MAX 7219. AS1100 is offered in a 24 pins PDIP and SOIC package.
