SLE 66CLX641P
General Description
The contactless only security controller SLE 66CLX641P is a member of the Infineon
Technologies SLE 66CxxxP high-end security controller family in 0.22 µm CMOS technology which
is designed for security systems that requires continuous ongoing improvements with the
highest degree of protection against fraudulent attacks.
SLE 66CLX641P is targeting contactless applications such like electronic passport, electronic
visas, national ID cards, banking, security access, digital signature and transport.
SLE 66CLX641P offers 134 Kbytes of User-ROM, 256 bytes internal RAM, 4 Kbytes XRAM,
700 bytes Crypto RAM and 64 Kbytes EEPROM, which can be used as data and as program
memory. The non-volatile memory consists of high reliability cells to guarantee data integrity. This
is especially important when the EEPROM is used as program memory.
It features both ISO/IEC 14443 Type A and B contactless interfaces on a single chip. It also
supports symmetric and asymmetric public-key algorithm such like DES, 3DES, Elliptic Curves and
RSA independently of the communication mode.

The CPU provides the high efficiency of the 8051 instruction set extended by additional powerful
instructions with enhanced performance, memory sizes and security features tailored for contact
and contactless smart card applications. Using the embedded PLL, the internal clock is adjustable
up to 15 MHz independent from the carrier frequency of the magnetic field supplied by the
contactless terminal.
The Memory Management Unit allows a secure separation of the operating system and the
applications. Using the system/application mode, it allows to securely downloading applications in
the field after card personalisation. Using the MMU transparent mode allows keeping the memory
mapping for code compatibility to SLE 66CxxS family. These new features suit the requirements of
the new generation of operating systems.
