HITAG 1 stick transponder
FEATURES • Complete identification transponder for use in contactless applications • Operating frequency 125 kHz • Data transmission and supply energy via RF link, no internal battery • Low power EEPROM technology for writing distance that equals reading distance • Total memory size 2048 bits • Parts of memory can be write protected by the user • Effective communication protocol with outstanding data integrity check • Secure mutual authentication function • Encrypted data transmission • Anticollision protocol for handling of multiple transponders inside the field of the reader antenna • Special features: – User defined write protection – Unique 32-bit serial number for each transponder – Encrypted data transmission possible. GENERAL DESCRIPTION The HITAG(1) stick transponder HT1DC20S30, based on the HITAG tag IC, is a high performance transponder for bi-directional data transmission in full-duplex mode. Data is stored in the transponder in a non-volatile memory (EEPROM).

HT1DC20S30
The transponder acts as a passive device, thus not having the need for any internal power supply (battery). It derives power from the magnetic component of the RF resonant frequency generated by the reader. Data is transmitted by modulating this resonant frequency. The HT1DC20S30 is dedicated for use in secure access systems where the transponder and the reader have to identify each other. The EEPROM has a capacity of 2048 bits and is organised in 64 pages. Access is provided either in page mode or in block mode, where 1 block includes 4 pages. Data transmission from the HT1DC20S30 to the reader uses Manchester or biphase coding and Amplitude Shift Keying (ASK) modulation. Absorpt...
