= 25°C and nominal supply voltage (5V).
(6) t
WR
is the minimum cycle time to be allowed from the system perspective unless polling techniques are used. It is the maximum
time the device requires to automatically complete the internal write operation.
The write cycle time is the time from a valid stop condition of a write sequence to the end of the internal erase/write
cycle. During the write cycle, the X24C04 bus interface circuits are disabled, SDA is allowed to remain HIGH, and
the device does not respond to its slave address.
