LD71D1048C
SD-2003A
10 bit PWM controller / 48 Channel Output LED DRIVER
PIN NAME
DESCRIPTION
VDD
5V Power supply terminal.
GND
GND terminals for LED Drivers and control logic.
All GND terminals must be connected to GND level.
Do not leave any GND terminal to NC.
DIN0 ~ DIN9
Data input terminals for 10Bit R, G, B data.
Shift register accepts R, G, B data from these terminals.
(at rising edge of SCKIN)
DOUT0 ~ DOUT9
Output terminals of shift register output data for next
DIN9 ~ DIN0 terminals.
RESETB
Reset input terminal (Low active).
This Pin reset all register except RAM Area.
SCKIN
Shift register clock input terminal.
STINB
Strobe signal input terminal. At falling edge of strobe signal,
48 channels of 10 bit data registers copy R, G, B data from
shift register.
STENB
STINB enable signal input terminal (Low active).
SCKEN
SCKIN enable signal input terminal (High active).
OEB_R
OEB_G
OEB_B
Output enable signal input terminal.
The device outputs data when OEB = “L”. When OEB = “H”
all R, G, B output terminals hold high-impedance state.
OEB_R, OEB_G, OEB_B work indepantant respectively.
R pin : COUT1,4,7,10,13,16,19,22,25,28,31,34,37,40,43,46
G pin : COUT2,5,8,11,14,17,20,23,26,29,32,35,38,41,44,47
B pin : COUT3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,48
