DATA SHEET
10MHz Serial Interface Individual LED Segment Control Decode/No-Decode Digit Selection 20A Low-Power Shutdown (Data Retained) Extremely low Operating Current 0.5mA in open loop Digital and Analog Brightness Control Display Blanked on Power-Up Drive Common-Cathode LED Display Software Reset 1 Optional External clock 24-Pin DIP and SO Packages Fully compatible to MAX7219
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 20A. and an operational current of less than 500A. 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.
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. It 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 set……
