Interfacing the NCP1840 LED Driver to an I2C Serial EEPROM
More InfoLess Info
Learn how this LED driver allows for full programmability of eight separate LED channels through internal registers via a simple I2C serial communication interface. Attaching a serial electrically erasable programmable read-only memory (EEPROM) device allows you to store calibrations of the luminance, color, and/or dimming of each of LED channel for future use. The calibrated settings can be restored at any time, including upon power-up.
