Write Cycle Time (see Figure 7) 5 ms
The write cycle is the time from a valid stop condition of a write sequence to the end of the internal program/erase cycle. During the write
cycle, the bus interface circuits are disabled, SDA is allowed to remain high and the device does not respond to its slave address.
