SLE 66C162P
General Description
SLE 66C162P is another member of Infineon Technologies high-end security controller family in
advanced 0.25 µm CMOS technology. The CPU provides the high efficiency of the SAB 8051-
instruction set extended by additional powerful instructions together with enhanced performance,
memory sizes and security features. The internal clock frequency can be adjusted up to 15 MHz
independent of the clock rate of the terminal with the help of the PLL.
The controller IC offers 70 Kbytes of User-ROM, 256 bytes internal RAM, 2048 bytes XRAM and
16 Kbytes Slim-EEPROM. The Memory Management and Protection Unit allows a secure
separation of the operating system and the applications. Furthermore the MMU makes a secure
downloading of applications possible after the personalization of a card. These new features suit
the requirements of the next generation of multi application operating systems. For code
compatibility to the SLE 66CxxS family, a transparent mode for the MMU is established which
allows to keep the memory mapping of the SLE 66CxxS products.

The CRC module allows the easy generation of checksums according to ISO/IEC 3309 (16-Bit-
CRC). To minimize the overall power consumption, the chip card controller IC offers a sleep mode.
The UART supports the half-duplex transmission protocols T=0 and T=1 according to ISO/IEC
7816-3. All relevant transmission parameters can be adjusted by software, as e.g. the clock
division factor, direct/inverse convention and the number of stop bits. Additionally, the I/O port can
be driven by communication routines realized in software.
The random number generator (RNG) is able to supply the CPU with true random numbers on all
conditions.
As an important feature, the chip provides a new and enhanced level of on-chip security.
In conclusion, the SLE 66C162P fulfills the requirements of today's chip card applications, as
GSM, and offers a powerful platform for future multi application cards. The SLE 66C162P
integrates outstanding memory sizes, additional peripherals in combination with enhanced
performance and optimized power consumption on a minimized die size. Therefore, the SLE
66C162P offers the basis for a generation of new chip card applications.
