Faster smartcard controllers

25 September 2002 DSP, Micros & Memory

Infineon's 66Plus series smartcard controllers are based on the same CPU platform as the successful 66S family, but offers larger RAM, ROM and EEPROM sizes and higher performance. It uses existing 66S software and has improved hardware security and fast calculation of cryptographic algorithms, as well as a memory management and protection unit. The latter separates the operating system from the different applications and supports secure multi-applications and loading of software in the field. The faster calculation of the crypto-algorithms and the higher CPU performance driven by the phase-locked loop shortens the transaction time in all applications. Advanced 0,25/0,22 µm embedded nonvolatile memory technology reduces die sizes which also improves mechanical reliability and reduces cost of silicon ¤ offers 500 000 read/write cycles for the EEPROM and more than 10 years data retention.
