SLE66CX640P

SLE 66CX640P 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 SLE 66CX640P offers 135 Kbytes of User-ROM, 256 byte internal RAM, 4096 byte XRAM and 64 Kbytes 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.
