ST19WR66 Dual Contact and Contactless Smartcard MCU with 66K bytes of Eeprom

The product, member of the ST19W platform, is a serial access microcontroller specially designed for cost effective secure portable applications.

It is manufactured using an advanced highly reliable ST CMOS EEPROM technology.

It is based on the STMicroelectronics 8 bit CPU already implemented on the ST19X product family and includes on-chip memories: User ROM, User RAM and EEPROM with state of the art security features. ROM, RAM and EEPROM memories can be configured into partitions with customized access rules.

An additional ST ROM contains all ST provided functions and libraries.

Access from any memory area to another are protected by hardware FIREWALLS. Access rules are User defined and can be selected by mask options or during the life of the product.

The chip includes an Enhanced DES accelerator which is accessible via cryptographic software libraries located in ST ROM.

The chip includes also a MAP which is based on a 1088 bits processor architecture. It processes modular multiplication, squaring and additional calculations up to 2176 bit operands.

Internal Modular Arithmetic Processor (MAP) and enhanced DES accelerator are designed to speed up cryptographic calculations using Public Key Algorithms and Secret Key Algorithms.

An RF Inteface including an RF Universal Asychornous Receiver Transmitter (UART) enables contactless communication up to 848 Kbits/s compatible with the ISO 14443-N standard.

As with all the other ST19W products, a serial interface fully compatible with the ISO7816 standard for Smartcard applications is available.

A CRC calculation block is also available and is directly accessible by the User
