SLE 44R35S is designed for single applications (e.g. access control or electronic tickets) with small
memory requirements. SLE 44R35S consists of an EEPROM memory of 1 Kbyte organised in
16 sector with 4 blocks each containing 16 bytes, an analogue interface for contactless energy and
data transmission and a control unit. The power supply and data are transferred to SLE 44R35S
via an antenna which consists of a coil with a few turns directly connected to the chip. No further
external components are necessary. The circuit is designed to communicate with a card reader at
an operating distance between 0 cm and 10.0 cm.

The internal logic ensures the recognition of several cards in the field which may be selected
and operated simultaneously
$XWKHQWLFDWLRQ/RJLF
Preceding any memory operation the authentication procedure with secret keys for the single
sector ensures permitted memory access only
&RQWURO/RJLF
The memory can only be accessed according to the access conditions programmed for every
block

: 16 sectors with 4 blocks each containing 16 bytes. The last block of each sector is
called "trailer" and stores a pair of secret keys and programmable access conditions for each
block
