General Description

SLE 66C320S 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 32 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 66C320S fulfills the requirements of all chip card applications, as

especially SIM Cards for GSM Phones (SIM-Toolkit), Multiapplication, Banking and Pay-

TV. The SLE 66C320S 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 66C320S offers

the basis for new chip card applications.
