SLE 66R35 consists of an EEPROM memory of 1 Kbyte organized in 16 sector with 4 blocks each
containing 16 bytes, an analog interface for contactless energy and data transmission and a
control unit. The power supply and data are transferred to SLE 66R35 via an antenna, which
consists of a coil with few turns directly connected to the module. No further external components
are necessary. The circuit is designed to communicate with a card-reader at an operating distance
of up to 10 cm (or more) depending on the reader-antenna configuration.

Short Product Information
Analog Contactless Interface:
The Analog Contactless Interface comprises the voltage rectifier, voltage regulator and system
clock to supply the IC with appropriate power. Additionally the data stream is modulated and
demodulated.
Anticollision
Internal logic of SLE 66R35 ensures the recognition of several cards in the field, which may be
selected and operated in sequence.
Authentication Logic
Correct execution of any memory operation can only occur after the authentication procedure
with a specific key.
Control Logic
Access to a block is defined by the associated access conditions for that block. These are
programmed individually for each block in a sector.
Arithmetic Unit
Arithmetic Capability: Increase and decrease of values stored in a special redundant format.
EEPROM: 1 Kbyte organized in 16 sectors with 4 blocks by 16 bytes each. Last block of each
sector is called "Sector Trailer" and used for a pair of secret keys and programmable access
conditions for each block.
