ST16RF52

2/2

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 in-

cludes 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 con-

figured 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 Ma-

trix (MACM).

Reliability data related to the ST16RF52 product,

manufactured

using

STMicroelectronics’

ad-

vanced 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.
