特点：
- led matrix driver (8x16)
8-channel pmos sws and 16-ch current drivers with 1/8 timing driven sequentially. - put on/off (for every dot).
- the current drivers can drive 0 to 20ma current with 16-step (for every dot).
- the current drivers can drive maximum 42.5ma/line.
- 64-steps of the luminance control by pwm (common setting for all dots)
- interface
- spi and i²c bus fs mode（max 400khz）compatibility
- for i²c mode, i²c device address is selectable (74h or 75h)
- thermal shutdown (tsd)
