The write cycle time is the time from a valid stop
condition of a write sequence to the end of the internal
bus interface circuits are disabled, SDA is allowed to remain
high, and the device does not respond to its slave
erase/program cycle. During the write cycle, the X24012

is the minimum cycle time from the system perspective when polling techniques are not used. It is the maximum time the device
requires to perform the internal write operation.
