ST16ST2G

Smartcard MCU With up to 16352 Bytes EEPROM & T2G+ Authentication Library

STMicroelectronics 

ST16ST2G

DESCRIPTION

The ST16ST2G, a member of the standard

ST16SF4x device family, is a serial access micro-

controller especially designed for high volume and

cost competitive Smartcard applications where

firmware security algorithm must be implemented.

The ST16ST2G is based on 8 bit CPU core and in-

cludes on chip memories: 384 Bytes of RAM, 15 K

Bytes of USER ROM, 1.5 K Byte of SYSTEM

ROM, and up to 16352 Bytes of EEPROM. The

ST16ST2G also includes 1 KByte of T2G+ Authen-

tication Library.

Both ROM and EEPROM memories can be config-

ured into two sectors. Access rules from any mem-

ory section or sector to any other are set-up by the

User’s defined Memory Access Control Matrix

(MACM).

Reliability data related to the ST16ST2G product

manufactured using STMicroelectronics advanced

CMOS EEPROM technology confirm data reten-

tion up to 10 years and endurance up to 100,000

Erase/Write cycles.

As with all other ST16 family members, the

ST16ST2G is fully compatible with the ISO stand-

ards for Smartcard applications.

Software development (ROM code, options) can

be completed by the ST16-19HDSE development

system.

The ST16ST2G can be delivered either in unsawn

or sawn wafers, 180 or 275 micron thickness as

well as in micromodule package.
