Note:
(1) Test Conditions according to "AC Test Conditions" Table.
(2) This parameter is characterized initially and after a design or process change that affects the parameter. Not 100% tested.
(3) 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.
(4) tPUR and tPUW are the delays required from the time VCC is stable until the specified operation can be initiated.
