(Note 3)
Note 3
: The write cycle time (t
) 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
NM24C02/03 bus interface circuits are disabled, SDA is allowed to remain high per the bus-level pull-up resistor, and the device does not respond to its slave address. Refer
"Write Cycle Timing" diagram.
