ST16601

Smartcard MCU With 1088 Bytes EEPROM

STMicroelectronics 

ST16601

DESCRIPTION

The ST16601, 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 ST16601 is based on 8 bit CPU core and in-

cludes on chip memories: 128 Bytes of RAM, 6

KBytes of USER ROM, 1 KByte of SYSTEM ROM,

and 1088 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 ST16601 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 ST16601 is

fully compatible with the ISO standards for Smart-

card applications.

Software development (ROM code, options) can

be completed by the ST16-19HDS development

system.

The ST16601 can be delivered either in unsawn or

sawn wafers, 180 or 275 micron thickness as well

as in micromodule package.
