Description

The ST16SF42, a member of the standard ST16 device family, is a serial access microcontroller especially designed for high volume and cost competitive Smartcard applications where firmware security algorithm must be implemented.

The ST16SF42 is based on 8 bit CPU core and includes on chip memories: 384 Bytes of RAM, 16KBytes of USER ROM, 1.5 KByte of 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 (MACM).

Reliability data related to the ST16SF42 product manufactured using STMicroelectronics advanced CMOS EEPROM technology confirm data retention up to 10 years and endurance up to 300,000 Erase/Write cycles.

As all other ST16 family members, the ST16SF42 is fully compatible with the ISO standards for Smartcard applications. Software development (ROM code, options) can be completed by the ST16-19HDS development system.

The ST16SF42 can be delivered either in unsawn or sawn wafers, 180 or 275 micron thickness as well as in micromodule package.
