The Advanced Crypto Engine is equipped with its own RAM of 700 bytes and supports all
of today known public-key algorithms based on large integer modular arithmetic. It allows
fast and efficient calculation of e.g. RSA operations with key lengths up to 2048 bit.
The Random Number Generator (RNG) is able to supply the CPU with true random
numbers on all conditions. The CRC module allows the easy generation of checksums
according to ISO 3309 (16-Bit-CRC).. 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 IC offers a sleep mode.
As an important measure, the chip provides a new and enhanced level of on-chip security
features.
In conclusion, the SLE 66CX160S fulfills the requirements of all chip card applications, as
especially information security, access control, payment and health care. The SLE
66CX160S is a powerful chip card cryptocontroller IC integrating outstanding memory
sizes, an extended crypto-coprocessor, additional peripherals in combination with
enhanced performance and optimized power consumption on an minimized die size.
Therefore, the SLE 66CX160S offers the basis for new chip card applications.
