NOTE:
Pins designated as "NC" are typically unbonded pins. However some of them are bonded for special testing purposes. Hence if a signal is applied to these pins, care
should be taken that the voltage applied on these pins does not exceed the V
CC
applied to the device. This will ensure proper operation.

Note 1:
Typical values are T
A
= 25°C and nominal supply voltage of 5V for 4.5V-5.5V operation and at 3V for 2.7V-4.5V operation.
Note 2:
This parameter is periodically sampled and not 100% tested.
Note 3:
The "L" and "LZ" versions can be operated in the 2.7V to 5.5V V
CC
range. However, for a standby current (I
SB
) of 1µA, the V
CC
should be within 2.7V to 4.5V.

Note 4:
The write cycle time (t
WR
) 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
FM24C08U/09U 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
