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.
Note:
(1) This parameter is tested initially and after a design or process change that affects the parameter.
(2) t_PUR and t_PUW are the delays required from the time V_CC is stable until the specified operation can be initiated.
