Fax: (+33) 4 42 25 87 29 1/2 1 ST16R820 DESCRIPTION The ST16R820, a member of the standard ST16 device family, is a serial access microcontroller especially designed for large volume contactless/ contact Smartcard applications. The ST16R820 is based on 8 bit CPU core and includes on chip memories: 192 Bytes of RAM, 8 KBytes of USER ROM, 4.5 KBytes of SYSTEM ROM, and 544 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). Reliability data related to the ST16R820 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.
