Note1: Comply with I2C timings for 1MHz operation - “Fast Mode Plus”.

Note2: No internal timeout for I2C operations, however, I2C communication state machine will be reset when entering UV/POR State.

Note3: This is an I2C system specification only. Rise and fall time of SCL & SDA not controlled by the device.

Note4: Device Address is factory configurable to 7’h1A, 7’h3A, 7’h5A.
