PIN DESCRIPTION

PIN NAME

FUNCTION

VDD

5 V Power supply terminal.

GND

GND terminals for LED Drivers and control logic.

All GND terminals must be connected to GND level.

Do not left any GND terminal to NC.

DIN8 ~ DIN0

Data input terminals for 9bit R, G, B data.

Shift register accepts R, G, B data from these terminals.

(at rising edge of SHCLK)

DOUT8 ~ DOUT0

Output terminals of shift register output data for next

DIN8 ~ DIN0 terminals.

/RESET

Reset input terminal (Low active).

SHCLK

Shift register clock input terminal.

STROBE

Strobe signal input terminal. At rising edge of strobe signal,

48 channels of 9 bit data registers copy R, G, B data from

shift register.

/CE1

Chip enable signal input terminal (Low active).

CE2

Chip enable signal input terminal (High active).

The device accepts SHCLK and STROBE when /CE1 = “L ”

and CE2 = “H ”.

OEB

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.

PWCLK

PWM generator reference clock input terminal.

BRMODE

Brightness control mode input terminal.

BRD2 ~ BRD0

Brightness control data input terminal.

PIN No.
