ST19CF68

The ST19CF68, a member of the ST19 device family, is a serial access microcontroller especially designed for very large volume and cost competitive secure portable objects, where high performance Public Key Algorithms will be implemented, to cut down initialization and communication costs and to increase security.

Its internal Modular Arithmetic Processor ST19CF68 is designed to speed up cryptographic calculations using Public Key Algorithms. Based on a 512 bit architecture, it processes modular multiplication and squaring up to1024 bit operands.

The ST19CF68 is based on a STMicroelectronics 8 bit CPU core including on-chip memories: 960 Bytes of RAM, 23 KBytes of USER ROM and 8 KBytes of EEPROM.

RAM, ROM and EEPROM memories ST19CF68 can be configured into partitions. Access rules from any memory partition to another partition are setup by the user defined Memory Access Control Logic.

ST19CF68 is manufactured using the highly reliable ST CMOS EEPROMtechnology.

As all other ST19 family members, ST19CF68 is fully compatible with the ISO standards for Smartcard applications.
