TECHNICAL DATA
LED Driver IC
Description
IK6208
The IK6028 are anode-grid LED display drives 5.0V~18.0V with output size
– 8 digits x 9 segments and addition key scan function.
Serial interface(UART) provides connection with microprocessor.
PWM for Buzzer driving.

• Operation voltage for output LEDs: 5.0V ~ 18.0V
• 7-step individual dimming control for each grid
• OSC: built in (with external resistor) 500kHz @ R=12.1kΩ
• Pulse segment current: 27mA-39mA @ 8 digits x 9 segments
• Key scanning: 7x2 matrix
• Serial Interface(UART). Up to 57,600bps
• 2 Channel PWM
• Operation Temperature : -40 ~ 85°C
LQFP-32
Application

COMMAND 2: DATA SETTING COMMANDS
The Data Setting Commands executes the Data Write Mode for IK6208. The Data Setting Command,
the bits5 and 6 (b4, b5) are given the value of “0”. , bit7 (b6) is given the value of “1” while bit8 (b7) is
given the value of “0”. Please refer to the diagram below.
When power is turned ON, bit 4 to bit 1 (b3 to b0) are given the value of “0”.

COMMAND 3: ADDRESS SETTING COMMANDS
Address Setting Commands are used to set the address of the display memory. The address is
considered valid if it has a value of “00H” to 2FH”. If the address is set to 30H or higher, the data is
ignored until a valid address is set. When power is turned ON, the address is set at “00H”.
Please refer to the diagram below.
