SLE66CLX321P

The  contactless  only security controller SLE 66CLX321P 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 66CLX321P is targeting contactless applications such like electronic passport, electronic visas, national ID cards, banking, security access, digital signature and transport.

SLE 66CLX321P offers 134 Kbytes of User-ROM, 256 bytes internal RAM, 4 Kbytes XRAM, 700 bytes Crypto RAM and 32 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, 3DES, Elliptic Curves and RSA independently of the communication mode.
