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 memorie s can be configured into two sectors. Access rules from any
Figure 1 Block D ia gram
memory section or sector to any other are set-up
by the User’s defined Memory Access Control Matrix (M ACM) .
Reliability da ta related to the ST16 R820 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.
