SLE66C162P

SLE 66C162P 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 66C162P offers 70 Kbytes of User-ROM, 256 bytes internal RAM, 2048 bytes XRAM and 16 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 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.

 The CRC module allows the easy generation of checksums according to ISO/IEC 3309 (16-Bit-CRC). 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) SLE 66C162P is able to supply the CPU with true random numbers on all conditions.

As an important feature, the chip SLE 66C162P provides a new and enhanced level of on-chip security. In conclusion, the SLE 66C162P fulfills the requirements of today's chip card applications, as GSM, and offers a powerful platform for future multi application cards. The SLE 66C162P integrates outstanding memory sizes, additional peripherals in combination with enhanced performance and optimized power consumption on a minimized die size. Therefore, the SLE 66C162P offers the basis for a generation of new chip card applications.
