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. The function
(shown below) is used to calculate the CRC value.
To perform the calculation, 7 bytes of data are
filled into a memory buffer in the same order as
they are read from the part – i.e. byte7, byte6,
byte5, byte4, byte3, byte2, byte1 of the serial
number. The calculation is performed on the 7
bytes, and the result should match the final byte out
from the part which is byte0, the 8-bit CRC value.
