CXA2108Q  
Constant-Current Driver for Full Color LED Display  
For the availability of this product, please contact the sales office.  
Description  
The CXA2108Q is a 1,024-gradation LED driver  
which is ideal for full color LED displays. This IC has  
24 outputs and a maximum output current of 60mA.  
Time division allows driving of either two or six LEDs  
per output by connecting an external FET or other  
switch. The luminance (PWM) and drive current for  
each LED are set using the internal RAM. The LED  
type is common anode.  
80 pin QFP (Plastic)  
Features  
• 24 outputs: 10-bit (1,024-gradation) PWM current outputs  
• Maximum output current: 60mA  
• LED type: Common anode  
• 4-bit brightness function capable of switching the basic PWM pulse width in 16 steps  
• Time division allows driving of up to six LEDs with a single output, making it possible to configure a high  
definition display with few driver ICs.  
• Coarse Adj. (2 bits) and Fine Adj. (8 bits) output current adjustment for each LED makes it possible to drive  
R, G and B using the same output from the same IC. In addition, the characteristics variance of each LED  
can also be corrected.  
• All luminance (PWM) data and drive current data are set by writing to the internal RAM.  
• PWM emitting can be performed up to 15 times per frame to realize a screen with little flicker.  
• Two built-in PWM data RAM make it possible to set the next luminance data even during PWM operation.  
• Abnormal internal temperature detection circuit  
• Single 5V power supply  
• Surface mounting package (80-pin QFP)
