SLE 66CL160S
General Description
The dual interface controller SLE 66CL160S is a member of the Infineon Technologies high-end
security controller family in 0.6 µm CMOS technology. It contains a contactless and a contact-
based interfaces on a single chip and supports symmetric and public-key algorithm such like DES
and Elliptic Curve.
The CPU provides the high efficiency of the 8051 instruction set extended by additional powerful
instructions with enhanced performance.
The controller offers 31.5 Kbytes of User-ROM, 256 bytes internal RAM, 1 Kbytes XRAM and
16 Kbytes EEPROM. It suits the requirements of the new generation of operating systems.

In contactless operation, SLE 66CL160S is able to communicate with any Proximity Card Device
(PCD) defined in ISO/IEC 14443 such as the Infineon Contactless Reader Evaluation Kit 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 of
106 Kbit/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.
Different anticollision procedures can be realized in software with the help of one 16-bit timer.
Timers ease the implementation of advanced communication protocols such as T=1 and all other
time critical processes for contact-based and contactless communications. An additional interrupt
capability of the I/O module allows parallel operation of chip card and terminal.
To minimize the overall power consumption, the chip card controller can be set into sleep mode.
The random number generator (RNG) is able to supply the CPU with true random numbers under
all conditions.
The CRC module allows the easy generation of checksums according to ISO/IEC 3309 (16-Bit-
CRC).
