Unique Serial Number (FM24VN10 only)

The FM24VN10 device also incorporates a read-only

8-byte serial number. It can be used to uniquely

identify a pc board or system. The serial number

includes a 40-bit unique number, an 8-bit CRC, and a

16-bit number that can be defined upon request by

the customer. If a customer-specific number is not

requested, the 16-bit Customer Identifier is 0x0000.

The 8 bytes of data are accessed via a Slave Address

sequence similar to the Device ID. The serial number

can be read by the system 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

two bits are ‘Don’t care’ values. 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 0xCD to

read the serial number.

6. The master ends the serial number read

sequence by NACKing the last byte, thus

resetting the slave device state machine and

allowing the master to send the STOP

command.

The 8-bit CRC value can be used to compare to the

value calculated by the controller. If the two values

match, then the communication between slave and

master was performed without errors.
