Device ID
The FM24V02 and FM24VN02 devices incorporate a
means of identifying the device by providing three
bytes of data, which are manufacturer, product ID,
and die revision. The Device ID is read-only. It can
be accessed as follows:
1. The master sends a START command.
2. The master sends Reserved Slave ID 0xF8
3. The master sends the I2C-bus slave address
of the slave device it needs to identify. The
last bit is a ‘Don’t care’ value (R/W bit).
Only one device must acknowledge this byte
(the one that has the I2C-bus slave address).
4. The master sends a Re-START command.
5. The master sends Reserved Slave ID 0xF9
6. The Device ID Read can be done, starting
with the 12 manufacturer bits, followed by
the 9 part identification bits, and then the 3
die revision bits.
7. The master ends the Device ID read
sequence by NACKing the last byte, thus
resetting the slave device state machine and
allowing the master to send the STOP
command.
Note: The reading of the Device ID can be stopped
anytime by sending a NACK command.
