Functional description

For the detailed functional description, refer to Ref. 1.

6.1 Block description

The ICODE DNA 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).

6.2 Memory organization

The 2048-bit user accessible EEPROM memory is divided into 64 blocks. A block is the

smallest access unit. Each block consists of 4 bytes (1 block = 32 bits). Bit 0 in each byte

represents the least significant bit (LSB) and bit 7 the most significant bit (MSB),

respectively.

The entire memory is divided into 2 parts:

– Within the 2016-bit memory (63 blocks) area the user data are stored. Direct

read/write access with the standard READ and WRITE commands to this part of

the memory is possible depending on the related security and write protection

conditions.

– 16-bit counter

The last block of the EEPROM memory (block 63) contains the 16-bit counter and

the counter protection flag.

– Within this part of the memory all required security related information is stored,

such as access keys with related privileges, headers, customer ID (CID) or

originality signature. This memory area can only by accessed with the

READ_CONFIG or WRITE_CONFIG commands depending on the configuration.
