5.3.3 my-d™ IC (SRF55VxxP)
my-d™ ICs are specific ICs from Infineon. These labels show a different memory organization. Two
different modes of tags are supported: plain and secure mode.
different modes of tags are supported: plain and secure mode.
Two different cards with 320 bytes or 1k bytes EEPROM memory are available. The EEPROM
memory is divided into pages.
memory is divided into pages.
Each tag is split into two parts: The administrative blocks (00h, 01h, 02h) and the user area.
Administrative pages are read only and cannot be changed. User data is free for use. Additionally
user data pages can be locked. This procedure is irreversible.
