ST16SF48 Datasheet, PDF (2/2 Pages) STMicroelectronics – Smartcard MCU With 8176 Bytes EEPROM

ST16SF48
DESCRIPTION
The ST16SF48, 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 ST16SF48 is based on 8 bit CPU core and in-
cludes on chip memories: 384 Bytes of RAM, 16
KBytes of USER ROM, 1.5 KByte of SYSTEM
ROM, and 8176 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 ST16SF48 product
manufactured using STMicroelectronics ad-
vanced 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 ST16SF48
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 ST16SF48 can be delivered either in unsawn
or sawn wafers, 180 or 275 micron thickness as
well as in micromodule package.
