The only difference I see looking in datasheets again that AS3645A supports dual-led mode, by using STROBE signal in case of parallel interface or thru additional bits in I2C mode. Can you be more specific what exactly makes you feel that they are not compatible? -- Andy Shevchenko Intel Finland Oy
