Description
Serial Data Shift Clock
Serial Data Input
Mode Select input with internal pulldown
MODE = GND: Selects greyscale mode (see Setting Greyscale Brightness on page 12) .
MODE = V CC : Selects dot correction mode (see Setting Dot Correction on page 11) .
Constant-Current Outputs 0:7
Constant-Current Outputs 8:15
Error Output
0 = LED open detection or overtemperature condition is detected.
1 = Normal operation.
Serial Data Output
Greyscale Clock. Reference clock for greyscale PWM control
Test Pin. This pin must be connected to GND (AS1112) to ensure normal operation.
Test Pin. This pin must be connected to V CC (AS1112B, AS1112C) to ensure normal operation.
Reference Current Terminal
Power Supply Voltage
This pin must not be connected.
Power Down input with internal pulldown (AS1112)
0 = normal operation mode
1 = powerdown mode
Not Connected (AS1112B, AS1112C)
Ground
Blank Outputs
0 = OUT n outputs are controlled by the greyscale PWM control.
1 = OUT n outputs are forced off; the greyscale counter is reset.
Data Latch. The internal connections are switched by pin MODE.
For LD (MODE = GND), the greyscale register receives new data.
For LD (MODE = V CC ), the dot correction register receives new data.
Thermal Pad. This pin must be connected to GND to ensure normal operation.
