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

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.
