Cxle8785p is a parallel single line transmission four channel LED driver output control chip which is compatible with and extends DMX512 (1990) signal protocol

The chip contains power supply and voltage stabilizing circuit, time-based circuit, signal decoding module, data buffer, built-in oscillator, four channel constant current driver with a default output current of 17mA. At the same time, users can also adjust the required current through the external rext resistor, SPWM gray level of 65536, SPWM output, supporting output polarity reversal at the out end. The built-in EEPROM stores the chip address, and the data bus automatically writes the address once, which can exit the address writing state online without power on again.
