ST16RF52
DESCRIPTION
The ST16RF52, a member of the standard ST16
device family, is a serial access microcontroller
especially designed for large volume contactless/
contact Smartcard applications.
The ST16RF52 is based on 8 bit CPU core and includes on chip memories: 512 B ytes 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 (M ACM) .
Reliability dat a related to the ST1 6RF52 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.
