1 General Description
The AS1120 is an LCD direct-driver capable of driving
up to 46 LCD segments with one non-multiplexed back-
plane.
The device contains an integrated serial-to-parallel inter-
face and generates the necessary signals to drive LCD
panels.
Internal synchronous backplane signal regeneration
allows the device to mix different drivers with different
LCDs for superior brightness stability over a wide tem-
perature range. The device also supports external back-
plane signals.
The AS1120 was specifically designed to easily inter-
face with a variety of microprocessors and a wide range
of LCD panel types.
The AS1120 is available in a 64-pin LQFP package.
