8.7.2.1 Product information and configuration - Page 0
The first EEPROM page includes production data as well as configuration information.
ProductID: Identifier for this MFRC631 product, only address 01h shall be evaluated for
identifying the Product CLRC663, address 00h and 02h shall be ignored by software.
Version: This register indicates the version of the EEPROM initialization data during
production. (Identification of the Hardware version is available in the register 7Fh, not in
the EEPROM Version address. The hardware information in register 7Fh is hardwired and
therefore independent from any EEPROM configuration.)
Unique identifier: Unique identifier for this device
Manufacturer Data: This data is programmed during production. The content is not
intended to be used by any application and might be not the same for different devices.
Therefore this content needs to be considered to be undefined.

C-Address: Two possibilities exist to define the address of the I
2
C interface. This can be
done either by configuring the pins IF0, IF2 (address is then 10101xx, xx is defined by the
interface pins IF0, IF2) or by writing value into the I
2
C address area. The selection, which
of this 2-information pin configuration or EEPROM content - is used as I
2
C-address is
done at EEPROM address 21h (Interface, bit4)
Interface: This section describes the interface byte configuration.
