7.1 Block description
7.2 Memory organization
The ICODE SLIX-S IC consists of three major blocks:
The analog section provides stable supply voltage and demodulates data received from
the reader for processing by the digital section. The analog section’s modulation transistor
also transmits data back to the reader.
The digital section includes the state machines, processes the protocol and handles
communication with the EEPROM.
The label requires no internal power supply. Its contactless interface generates the power
supply and the system clock via the resonant circuitry by inductive coupling to the
interrogator. The interface also demodulates data that are transmitted from the
interrogator to the ICODE Label, and modulates the electromagnetic field for data
transmission from the ICODE Label to the interrogator.
Data are stored in a non-volatile memory (EEPROM).
The 2048 bit EEPROM memory is divided into 64 blocks. A block is the smallest access
unit. Each block consists of 4 bytes (1 block = 32 bits). 4 blocks are summed up to 1 page
for password protection. Bit 0 in each byte represents the least significant bit (LSB) and
bit 7 the most significant bit (MSB), respectively.
The memory is divided into 2 parts:
•
•
•
•
•
Analog RF interface
Digital controller
EEPROM
Configuration area
– Within this part of the memory all required information is stored, such as UID, write
User memory
– Within the 1280 bit memory area the user data are stored. Direct read/write access
protection, access control information, passwords, AFI and EAS. This memory
area cannot be directly accessed.
to this part of the memory is possible depending on the related security and write
protection conditions.
