SLE 66CL81P
Timers ease the implementation of advanced communication protocols such as T=CL (according
to ISO/IEC 14443-4) and all other time critical processes for contactless communications. Both
Timers features auto-reload mechanisms as well as their own dedicated interrupt vectors.
Additional interrupts capability of the RF interface module allows real time operation of the pure
contactless smart card with the contactless terminals.
SLE 66CL81P is able to communicate with any Proximity Card Device (PCD) defined in
ISO/IEC 14443 such as the Infineon Evaluation Kit Proximity over a typical coupling distance of
10 cm. The power supply and data are received by an antenna, which consists of a coil with a few
turns directly connected to the IC. DES acceleration by a factor of more than 500 compared to
software solutions in combination with the high data transfer rate up to 848Kbit/s keep the
transaction times short. For more independence and flexibility, the controller offers the two
modulation type A and type B according ISO/IEC 14443.
The Anticollision and Contactless Transmission Protocol are supported by open source
application notes for both Type A and B in order to offer a maximum flexibility to the
Operating System. Both Contactless Communication protocol may be implemented in the
Operating System while the final selection of the Type A or B is based upon the
personalisation data of the contactless smart card. The communication type can also be
changed during runtime in the field. Thus, SLE 66CL81P ensures a simplified handling of the
ROM mask, high reactivity by a tailored personalisation during production of the contactless
smart card in order to answer to the increasing market demand and applications.
SLE 66CL81P features a new Resource Management System (RMS_E) which optimizes
Contactless EEPROM write/erase routines. EEPROM programming is enhanced over the entire
communication distance compared to the standard RMS. Thus, the reduction of programming
times and power consumption is ensured independently of the use of the contact or the contactless
interface.
The CRC module allows the easy generation of checksums according to ISO/IEC 3309 (16-Bit-
CRC), thus it supports the two different CRC calculation required for ISO/IEC 14443 Type A and
Type B. Also, data as well as program located in the EEPROM can be extra-secured by a CRC
checksum enabling the Operating System to detect errors while downloading new application in
the field.
To minimize the overall power consumption, the contactless security controller can be set into
sleep mode.
The certified random number generator (RNG) is able to supply the CPU with true random
numbers on all conditions. It allows creating session key used for authentication in open networks
and enable secure downloading of new applications.
The DDES-EC2 accelerator consists of two modules.
The DDES module supports symmetrical crypto algorithms according to the Data Encryption
Standard in the Electronic Code Book Mode. It features two internal registers for storage of the two
keys required for a Triple DES computation. Together with the fast contactless interface, it offers
high security and high speed for contactless smart card applications.

The EC2 module accelerates the multiplication in GF (2
) and therefore the operations for elliptic
curve cryptography. It widens the field of application for SLE 66CL81P since it can be used as
tamper-resistant security tool for secured and authentic communication in open networks
and can be used in contactless operation.
As an important feature, SLE 66CL81P provides a new and enhanced level of on-chip
security, which fulfils the strong security requirements of a Common Criteria evaluation at
an EAL5 level. Each security measure is designed to act as an integral part of the complete
system in order to strengthen the system as a whole.
