SLE 66R35 / SLE 66R35I / SLE 66R35R consist 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 /SLE 66R35I / SLE 66R35R 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.
The chip is designed to meet the cost-optimized requirements of a
basic security level. The targeted applications are transport,
corporate access, events and loyalty cards with basic
security requirements.
• 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 / SLE 66R35I / SLE 66R35R ensures the
recognition of several cards in the field, which may be selected and operated in sequence.
The Anticollision loop is based on Single Size UID according to ISO/IEC 14443-3
• 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: increment and decrement of values stored in
a special redundant format.
• EEPROM: 1 kByte organized in 16 sectors with 4 blocks by 16 bytes
each. The last block of each sector is called "Sector Trailer" and is used to store a pair
of secret keys and programmable access conditions for each block.
