SLE 66CX320P is the first product of Infineon Technologies high end security controller family in advanced 0.25 m 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 SLE 66CX320P offers 63 Kbyte of User-ROM, 256 bytes internal RAM, 2048 bytes XRAM and 32 Kbytes EEPROM. The Memory Management 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.
