The ST19GF34, a member of the ST19 device family, is a serial access microcontroller especially designed for very large volume and cost competitive secure portable objects.

The ST19GF34 is based on a STMicroelectronics 8 bit CPU core including on-chip memories: 1984 Bytes of RAM, 56 K Bytes of USER ROM and 34 K Bytes of EEPROM.

RAM, ROM and EEPROM memories ST19GF34 can be configured into partitions. Access rules from any memory partition to another partition are setup by the user defined Memory Access Control Logic.

ST19GF34 is manufactured using the highly reliable ST technology.

As all other ST19 family members, ST19GF34 is fully compatible with the ISO standards for Smartcard applications.
