Product data sheet COMPANY PUBLIC Rev. 3.3 — 3 April 2012 171133 47 of 132 NXP Semiconductors CLRC663 Contactless reader IC 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 CLRC663 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.
