The transponder IC is designed to operate with a 13.56 MHz carrier frequency. The ISO standard defines for some communication parameters several modes in order to meet different international radio regulations and different application requirements. Therefore communication between the reader and the transponder (Down-Link communication) takes place using ASK modulation index between 10% and 30% or 100% and datacoding (pulse position modulation) ‘1 out of 4’ or ‘1 out of 256’. According to ISO 15693 Up-Link communication (Transponder to Reader) can be accomplished with one subcarrier (ASK modulation) or with two subcarrier (FSK modulation). Both modes (ASK and FSK) can operate with either high or low data rate. The transponder will answer in the mode it was interrogated from the reader and supports all communication parameter combinations. Up- and Down-Link are frame synchronized and CRC check sum secured. Each Tag-it HF-I Standard Transponder IC has a ‘unique’ address (UID) stored in two blocks which are factory-programmed and 64 bits long (=264 different addresses). This can be used for addressing each transponder uniquely and individually for a one-to-one exchange between the reader and the transponder. A mechanism to resolve collisions of a multiplicity of transponders (Anticollision) is also implemented. This special feature allows multiple transponders to be read simultaneously and offers the capability to inventory in a very short time a large number of transponders by their unique address, provided they are within the reader operating range. Also, the Application Family Identifier (AFI), which is optional in the ISO15693, is supported by the Tag-it HF-I Standard Transponder. For more details about the communication between reader and transponder see ISO/IEC 15693 and the Tag-it HF-I Standard Extended Command Specification. User data is read and stored in a 256 bit non-volatile user memory that is organized in 8 blocks. Each block with 32 bit is user programmable and can be locked individually to protect data from modification. Once set, the lock bit cannot be reset. The user memory is field programmable per block. Two levels of block locking are supported: Individual block locking by the user (U) or individual block locking of factory programmed data (F) during manufacturing. Bit 2 of the “Block Security Status” Byte defined in ISO 15693-3 is used to store the Factory Lock Status of the Block. Block locking irreversibly protects the locked data from any further reprogramming. Figure 1-2.
