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