The E521.36 is a one chip solution for RGB ambient light application. It provides an integrated 16-bit micro-controller with 32kByte memory, EEPROM, a LIN trans-ceiver supporting LIN auto-addressing. The integrated current sources can be controlled by a 16bit PWM with a 48MHz clock. This enables PWM cycle frequencies up to 700Hz with full resolution. Each driver can be used to drive external loads with currents up to 40mA. For power management and temperature compensation the device provides an integrated temperature sensor as well as an supply voltage sensing circuitry. Furthermore, with the ADC in the measurement system and the differ-ential measurement of the forward voltage an effective compensation for ageing and temperature can be imple-mented.
