7 / 8 page SLE 66C322P Short Product Information 7 / 8 08.01 General Description SLE 66C322P is another member of Infineon Technologies high-end security controller family in advanced 0.22 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 10 MHz independent of the clock rate of the terminal with the help of the PLL. The controller IC offers 134 Kbytes of User-ROM, 256 bytes internal RAM, 4096 bytes XRAM and 32 Kbytes Slim-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 meet 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 available which allows you to keep the memory mapping of the SLE 66CxxS products.

To minimize the overall power consumption, the chip card controller IC offers a sleep mode. The UART supports the half-duplex transmission protocols T=0 and T=1 according to ISO/IEC 7816-3. All relevant transmission parameters can be adjusted by software, as e.g. the clock division factor, direct/inverse convention and the number of stop bits. Additionally, the I/O port can be driven by communication routines realized in software. The random number generator (RNG) is able to supply the CPU with true random numbers under all conditions. As an important measure, the chip provides a new and enhanced level of on-chip security features. |
