The AS1120 LCD driver is well suited for use in standard and custom LCDs in industrial applications such as gas station displays, process monitoring and equipment displays, instrumentation readouts, digital clocks, and thermometers. This RoHS-compliant LCD driver supports both alphanumeric and bar graph displays and is available in a 64-pin PQFP package. The chip can drive up to 46 segments of non-multiplexed LCD displays. However, the chip can be cascaded to increase this number. The serial interface allows for simple integration into microprocessor-based solutions, with minimal interface required between the display and data source. The AS1120 offers ultra-low current consumption of 5 mA, enhanced brightness stability over a wide temperature range, and a power supply input ranging from 3 to 5.5 V. Individual segment control enables custom display applications for a wide variety of specifications.
