Datasheet
1 General Description
The AS1100 is an LED driver for 7 segment numeric displays of up to
8 digits. The AS1100 can be programmed via a conventional 4 wire
serial interface.
The device includes a BCD code-B decoder, a multiplex scan
circuitry, segment and display drivers, and a 64 Bit memory. The
memory is used to store the LED settings, so that continuous
reprogrammng is not necessary.
Every individual segment can be addressed and updated separately.
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 offered in a 24-pin DIP and SOIC packages.
