Features & Applications

The AS1105WL is a LED driver for 7 segment numeric displays of up to 4 digits. It 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 32-Bit memory. The memory is used to store the LED settings, so that continuous reprogramming 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.

Features:

  • 10MHz Serial Interface
  • Individual LED Segment Control
  • Decode/No-Decode Digit Selection
  • 20 µA Low-Power Shutdown (Data Retained)
  • Extremely low Operating Current 0.5 mA in open loop
  • Digital and Analog Brightness Control
  • Display Blanked on Power-Up
  • Drive Common-Cathode LED Display
