Revision 1.00
+3.0V to +5.5V
The output current drivers of the AS1112 can handle up to +15V.
Can be directly connected to OUT (E) of the previous board.
Can be directly connected to IN (D) of the next board.
Description follows below.
0: Open or Temp. Error Detected 1: Normal Operation
Reference clock for grayscale PWM control.
(MODE = GND): the greyscale register receives new data.
(MODE = VCC): the dot correction register receives new data.
0 = OUTn outputs are controlled by the greyscale PWM control.
1 = OUTn outputs are forced off; the greyscale counter is reset.
Input with internal pulldown
MODE = GND: Selects greyscale mode
MODE = VCC: Selects dot correction mode
This jumper must be set if only a single board is in use, or on the
last board in a daisy chain.
Input with internal pulldown
0 = normal operation mode
1 = powerdown mode
Place resistor here to set the load current.
Connector for LED’s. Upper side interfaces with the output drivers
of the AS1112 while the bottom line connects to VLED.
Jumper to (dis)connect the onboard capacity.
