Description

The contactless only security controller SLE 66CL81P is a member of the Infineon Technologies SLE 66CxxxP high-end security controller family in 0.22 µm CMOS technology which is designed for security systems that requires continuous ongoing improvements with the highest degree of protection against fraudulent attacks.

SLE 66CL81P is targeting secure contactless applications such like electronic visa, national ID card, banking, security access, digital signature and transport.

SLE 66CL81P offers 70 Kbytes of User-ROM, 256 bytes internal RAM, 2048 bytes XRAM and 8 Kbytes EEPROM, which can be used as data and as program memory. The non-volatile memory consists of high reliability cells to guarantee data integrity. This is especially important when the EEPROM is used as program memory.

It features both ISO/IEC 14443 Type A and B contactless interfaces on a single chip. It also supports symmetric and asymmetric public-key algorithm such like DES and Elliptic Curve independently of the communication mode.
