General Description
SLE 66C40S is a member of the Infineon Technologies high-end security controller family
in 0.6 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 controller IC offers 31.5 Kbytes of User-ROM, 256 bytes internal RAM, 1 Kbyte XRAM
and 4 Kbytes EEPROM. It suits the requirements of the new generation of operating
systems.

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). The timer makes it easy to implement advanced
communication protocols such as T=1 and all other time critical processes. 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 66C40S fulfills the requirements of all chip card applications, as
especially SIM Cards for GSM Phones, payment, Health Care, Pay-TV and Access
Control. The SLE 66C40S is a powerful chip card controller IC integrating outstanding
memory sizes, additional peripherals in combination with enhanced performance and
optimized power consumption on a minimized die size. Therefore, the SLE 66C40S offers
the basis for new chip card applications.
