I/O DESCRIPTION
NAME RHB NO. DAP NO.
Blank (all constant-current outputs off). When BLANK is high, all constant-current outputs (OUT0
through OUT23) are forced off, the grayscale PWM timing controller initializes, and the grayscale
BLANK 30 2 I
counter resets to '0'. When BLANK is low, all constant-current outputs are controlled by the
grayscale PWM timing controller.
GND 29 1 — Power ground
This pin sets the constant-current value. OUT0 through OUT23 constant sink current is set to the
IREF 27 31 I/O
desired value by connecting an external resistor between IREF and GND.
Constant-current output. Multiple outputs can be tied together to increase the constant-current
OUT0 1 5 O
capability. Different voltages can be applied to each output.
OUT1 2 6 O Constant-current output
OUT2 3 7 O Constant-current output
OUT3 4 8 O Constant-current output
OUT4 5 9 O Constant-current output
OUT5 6 10 O Constant-current output
OUT6 7 11 O Constant-current output
OUT7 8 12 O Constant-current output
OUT8 9 13 O Constant-current output
OUT9 10 14 O Constant-current output
OUT10 11 15 O Constant-current output
OUT11 12 16 O Constant-current output
OUT12 13 17 O Constant-current output
OUT13 14 18 O Constant-current output
OUT14 15 19 O Constant-current output
OUT15 16 20 O Constant-current output
OUT16 17 21 O Constant-current output
