tWR(6)
Write Cycle Time
Min.
The write cycle time is the time from a valid stop
condition of a write sequence to the end of the internal
erase/program cycle. During the write cycle, the X24C04

Notes: (5) Typical values are for TA = 25°C and nominal supply voltage (5V).
(6) tWR 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.
