General Description
The PCF7936, HITAG 2 is a programmable Security
Transponder employing mutual authentication ideally
suited for contactless authentication and memory
access between a basestation and the transponder.
The transponder meets the security and performance
requirements of modern vehicle immobiliser
applications. Excellent device sensitivity (large
distance) and short authentication time ensure easy
application and outstanding system performance.
The transponder provides 256 bit of non-volatile
memory (EEPROM) from which 128 bit are reserved
for user data storage. User data and configuration data
may be exchanged in cipher mode for advanced pre-
personalisation techniques. Memory access flags
support read and/or write protection of data.
The device performs a fast mutual authentication
algorithm, employing a Random Number, Secret Key
and Passwords. In addition the HITAG 2 features a
factory programmed 32 bit unique identification number
to enable unambiguously device identification.
The HITAG 2 features two Read Only modes for
downward compatibility with common Read Only
systems.
The transponder power supply and system clock is
derived from the magnetic component of the RF field
generated by the basestation. Due to low power
consumption the HITAG 2 provides excellent sensitivity
in read and write mode.
The transponder is assembled in a small leadless stick
shaped plastic package.
