General description

HITAG 1 based transponders are highly integrated and do not need any additional

components beside the external coil.

Data between Key (RWD) and transponder is transmitted bidirectionally, in Half Duplex

Mode. The HITAG 1 transponder IC offers also an encrypted data transmission.

The AntiCollision (AC) Mode, which is used mainly in long range operation, allows to

handle several transponders that are at the same time in the communication field of the

antenna, thus achieving highest operating reliability and permitting to handle several

transponders quickly and simultaneously.

The HITAG 1 transponder IC provides two protocol modes, Standard and Advanced

Mode. The Advanced Protocol Mode operates compared to the Standard Protocol Mode

with an increased number of Startbits and a 8-bit Cyclic Redundancy Check (CRC) sent

by the transponder IC at read operations.

HITAG 1 transponder IC offer a memory of 2 kbit.
