The evaluation system is composed of a motherboard, daughter-board, and LED subboard. The motherboard provides the I2C signals from the PC USB port and generates the I/O voltages and digital high and low signals for the daughterboard. For overtemperature measurement, the daughterboard can be either plugged directly into the motherboard or connected to the motherboard via a ribbon cable.
The motherboard features a 3.3 V regulator and 2.8 V/1.8 V regulators for VDDIO. The daughterboard contains jumpers and test points for easy evaluation of the flash driver integrated circuit (IC).
