7.5 Device ID - PCA9698 ID field
The Device ID field is a 3 byte read-only (24 bits) word giving the following information:
The Device ID is read-only, hard-wired in the device and can be accessed as follows:
For the PCA9698, the Device ID is as shown in
1. START command
2. The master sends the Reserved Device ID I
3. The master sends the I
4. The master sends a Re-START command.
5. The master sends the Reserved Device ID I
6. The Device ID Read can be done, starting with the 12 manufacturer bits (first byte +
7. The master ends the reading sequence by NACKing the last byte, thus resetting the

12 bits with the manufacturer name, unique per manufacturer (e.g., NXP)
9 bits with the part identification, assigned by manufacturer (e.g., PCA9698)
3 bits with the die revision, assigned by manufacturer (e.g., RevX)
set to ‘0’ (write): ‘1111 1000’.
The LSB is a ‘Don’t care’ value. Only one device must acknowledge this byte (the one
that has the I
Remark: A STOP command followed by a START command will reset the slave state
machine and the Device ID Read cannot be performed. Also, a STOP command or a
Re-START command followed by an access to another slave device will reset the
slave state machine and the Device ID Read cannot be performed.

second byte + 5 MSBs of the third byte), and then the 3 die revision bits (3 LSBs of
the third byte).
slave device state machine and allowing the master to send the STOP command.
Remark: The reading of the Device ID can be stopped anytime by sending a NACK
command.
If the master continues to ACK the bytes after the third byte, the PCA9698 rolls back
to the first byte and keeps sending the Device ID sequence until a NACK has been
detected.
