• Description: Intelligent Eeprom With Contactless Interface Compliant To
• Manufacturer: Infineon Technologies Corporation

The User Area stores User Data in up to 125 pages. Data in the plain sector are accessible
both via ISO optional and ISO custom commands.
The Service Area stores the UID, manufacturer data and configuration data. This information
is programmed at manufacture of the chip and cannot be changed. Data are accessible via
ISO custom commands only, except the UID being available also via the Inventory command.
The Administration Area stores 2 bytes of information about page administration (SI - Sector
Index and AC - Access Condition).
- Sector Index (SI) defines plain memory access
- Access Condition (AC) holds information on access rights (e.g. read/write, read only)
The Sector Index and Access Condition of each page store each bit non-inverted and inverted
to ensure data integrity.
Data are accessible via ISO custom commands only.
