SLE 66R35E7 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 66R35E7 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.

Preliminary Short Product Information
Analog Contactless Interface:
– The Analog Contactless Interface comprises the voltage rectifier, voltage regulator and system clock to
Anticollision
– Internal logic of SLE 66R35E7 ensures the recognition of several cards in the field which may be selected
Authentication Logic
– Correct execution of any memory operation can only occur after the authentication procedure with a specific
Control Logic
– Access to a block is defined by the associated access conditions for that block. These are programmed
Arithmetic Unit
– Arithmetic Capability: increment and decrement of values stored in a special redundant format.
EEPROM:
