Product information and configuration - Page 0

The first EEPROM page includes production data as well as configuration information.

ProductID: Identifier for this MFRC630 product

Version: Silicon Version identifier.

ManufacturerData: 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.

I2C-Address: Two possibilities exist to define the address of the I2C 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 I2C address area. The selection, which

of this 2-information pin configuration or EEPROM content - is used as I2C-address is

done at EEPROM address 21h (Interface, bit4)

Interface: This section describes the interface byte configuration.
