Data are stored in the transponder in a non-volatile memory (EEPROM). The transponder requires no internal power supply; it derives its power from the magnetic component of the RF carrier frequency generated by the reader. Data are transmitted by modulating this carrier. The HT2DC20S20 is dedicated for use in secure access systems where the transponder and the reader have to identify each other. The choosable use of cryptography enables highest data security. Providing several operating modes (password, crypto, standard read only modes) the versatile transponder can be used in various applications. The possible use of an installed reader base for read only transponders makes the additional use of HT2DC20S20 or the replacement of read only transponders by HT2DC20S20 very easy. The HALT-command can be used after finishing data exchange to reach the halt-state. In this state the transponder is muted. This feature can be used to have steady RF field where single transponders are collected one by one. Each transponder is operated and then disabled so it does not interfere with the next transponder. The halt-state can only be exited by switching off/removing the magnetic field. The EEPROM has a capacity of 256 Bits and is organized in 8 pages of 4 Bytes. The 8 pages are split up into 4 pages containing user data and into 4 pages for control of the memory access and for authentication purposes. The pages of the transponder memory can be protected against read or write access by setting corresponding memory flags. Absorption modulation is used to transmit data from the transponder to the reader. The transponder absorbs the magnetic field, which hence modulates the current in the reader antenna. Data transmission to the HT2DC20S20 uses binary pulse length modulation (BPLM).

Depending on the operation mode the EEPROM is organized as described in the following. Crypto Mode: Page 0 1 2 3 4 5 6 7 Content Serial Number 32 LSBs of 48 bit key 16 MSBs of 48 bit Key, 16 bit reserved 8 bit Configuration, 24 Bit Password TAG read/write page read/write page read/write page read/write page Password Mode: Page 0 1 2 3 4 5 6 7 Content Serial Number Password RWD reserved 8 bit Configuration, 24 bit Password TAG read/write page read/write page read/write page read/write page Page 7 of 20 HITAG 2 Transponders Product Specification 3.0 July 2006 5.2 Operation Modes and Configuration With the Configuration Byte the operation mode and the access rights to the memory can be selected. During Power-Up of the transponder the Configuration Byte is read from the EEPROM of the transponder. If you change the configuration, keys or passwords, you have to place the transponder directly on the antenna (0-distance)! In order to avoid any errors do not move the transponder during this write process and be sure that you are in a safe environment without electrical noise. 5.2.1 Modes of Operation The HT2DC20S20 can be operated in several modes. Crypto Mode: Mode for writing or reading the transponder with encrypted data transmission. Password Mode: Mode for writing or reading the transponder with plain data transmission. Public Mode A (Manchester): Read only mode emulating Philips MIRO transponders resp. µEM H400x transponders. The 64 bits of the user Pages 4 and 5 are cyclically transmitted to the read/write device. Public Mode B (Biphase): Read only mode according to ISO standards 11784 and 11785 for animal identification. The 128 bits of the user Pages 4 to 7 are cyclically transmitted to the read/write device. Public Mode C (Biphase): Read only mode emulating the read operation of the PCF793X (with a slightly different Program Mode Check). In the Public Mode C the 128 bits of the user Pages 4 to 7 are cyclically transmitted to the read/write device. Page 8 of 20 HITAG 2 Transponders Product Specification 3.0 July 2006 5.2.2 Status Flow After entering the RF-field the transponder waits for a command to start the authentication. After issuing this command the mutual authentication takes place, followed by read- and write commands. In password mode the data transfer occurs plain, in crypto mode data are encrypted. The halt mode can be entered for muting a transponder. If the transponder is configured in one of the public modes, these modes are entered automatically after a certain waiting time and data pages are sent cyclically to the read/write device. By issuing the command to start the authentication during the waiting time also public mode transponders can be brought into the authorized state.

Page 12 of 20 HITAG 2 Transponders Product Specification 3.0 July 2006 5.4 Definition of Passwords and Keys Keys are cryptographic codes, which determine data encryption during data transfer between read/write device and transponder. They are used to select a HT2DC20S20 transponder in Crypto Mode. The 16 bit KEY HIGH and 32 bit KEY LOW form one 48-bit key which has to be identical on both the transponder and the read/write device. Passwords are needed to select a HT2DC20S20 transponder in Password Mode. There is one pair of passwords (Password TAG, Password RWD), which has to be identical both on the transponder and the read/write device. Password TAG: Password that the transponder sends to the read/write device and which may be verified by the latter (depending on the configuration of the read/write device). Password RWD: Password that the read/write device sends to the transponder and which is checked for identity by the latter. It is important that the following values are in accordance with each other, i.e. the respective data on the read/write device and on the transponder have to be identical pairs. HT2DC20S20 in Password mode: on the on the read/write transponder device Password RWD ⇔ Password RWD as an option (depending on the configuration of the read/write device): Password TAG ⇔ Password TAG HT2DC20S20 in Crypto mode: on the read/write device KEY LOW KEY HIGH on the transponder ⇔ ⇔ KEY LOW KEY HIGH as an option (depending on the configuration of the read/write device): Password TAG ⇔ Password TAG The passwords and keys are predefined by Philips by means of defined Transport Passwords and a Transport Key. They can be written to, which means that they can be changed (see also Chapter “Configuration of Delivered HT2DC20S20 Transponders“). ATTENTION: Passwords and Keys only can be changed if their current values are known!
