Note 3: The write cycle time (t
WR) is the time from a valid stop condition of a write sequence to the end of the internal erase/program cycle. During the write cycle, the
NM24C16U/17U bus interface circuits are disabled, SDA is allowed to remain high per the bus-level pull-up resistor, and the device does not respond to its slave address.
