Fax: (+1) 630-604-7026 1/2 1 ST16HF52 DESCRIPTION The ST16HF52, a member of the standard ST16 device family, is a serial access microcontroller especially designed for large volume contactless/ contact Smartcard applications. The ST16HF52 is based on 8 bit CPU core and includes on chip memories: 512 Bytes of RAM, 22 KBytes of USER ROM, SYSTEM ROM, and 2048 Bytes of EEPROM. Both ROM and EEPROM memories can be configured into two sectors. Access rules from any memory section or sector to any other are set-up by the User's defined Memory Access Control Matrix (MACM). The HyperProximity TM switch enables an insured connection between the card and an adequate reader, as with contact cards. High risk transactional based applications resident on the Smart card can use the switch to require that the Smart card be in a HyperProximity TM mode for the application to complete execution. Reliability data related to the ST16HF52 product, manufactured using STMicroelectronics' advanced CMOS EEPROM technology, confirm data retention of up to 10 years and endurance up to 300,000 Erase/Write cycles. Contact operation is fully compatible with the ISO standards for Smartcard applications. Figure 1 Block Diagram VCC GENERATION RAM 8 BIT CPU 512 bytes SYSTEM ROM ROM 22 Bytes EEPROM SECTORS COMBIN.
