Notes:
(1) This parameter is characterized initially and after a design or process change that affects the parameter. Not 100% tested.
(2) Test Conditions according to “AC Test Conditions” table.
(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.
