Pin Description
NAME PIN NO. I/O
DESCRIPTION
CMD[2:0] SDIP/SOP: I Encoded commands for data transfer, time division operation
22, 23, 24
and PWM display:
CMD[2:0]
Command
[000]: Mode-1 time division operation / No operation for
display
[001]: Mode-2 time division operation / No operation for
display
[010]: Data transfer enable (Shift-In)
[011]: Data latch strobe (Capture)
[100]: First LED emitting
[101]: Second LED emitting
[110]: LED emitting disable / IOUT disable (Stop)
[111]: Test mode
CMD commands are latched at the rising edges of DCLK.
There is one DCLK latency between Shift-in command
latched and data shift-in.
DIN SDIP/SOP: I Serial input for luminance data (time division mode-1/2)
25
DOUT SDIP/SOP: O Serial output for luminance data (time division mode-1/2).
18
DCLK SDIP/SOP: I Synchronous clock input for command and serial data
20 transfer. The input data of DIN is synchronous to rising edges
of DCLK, and transferred to DOUT on falling edges of DCLK.
GCLK SDIP/SOP: I Clock input for PWM operation.
19
IOUT0-15 SDIP/SOP: O LED driver outputs.
27, 28, 1, 2
3, 4, 5, 6, 9,
10, 11, 12
13, 14, 15,
16
REXT SDIP/SOP: O Driver current setting. LED current is set to a current value by
21 connecting an external resistor between REXT and GND.
VDD
SDIP/SOP: - Power supply
26
GND
SDIP/SOP: - Analog and digital ground
17
IGND SDIP/SOP: - Two ground-pin for driver outputs.
