Write Cycle Time

5

ms

The write cycle time 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.
