7 / 7 page SLE 66C20S Short Product Information 7 / 7 10.01 General Description SLE 66C20S 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 2 Kbytes EEPROM. It suits the requirements of the new generation of operating systems. EEPROM 2 Kbyte XRAM 1 Kbyte ROM 32 Kbyte 16-Bit CPU & ECO 2000 Instruction Set Voltage Clock Reset Sleep Mode Logic Sensors/Filters Voltage Regulator Address-/Data Bus 16-bit Timer Interrupt CRC Random Number Generator Figure 2: Block Diagram SLE 66C20S 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 66C20S fulfills the requirements of all chip card applications, as especially Loyalty, Leisure Cards, Health Care, payment, Access Control and prepaid SIM Cards for GSM Phones. The SLE 66C20S 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 66C20S offers the basis for new chip card applications. |
