ST19NA18数据手册ST中文资料规格书

描述 Description

The product, member of the ST19N 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 intopartitions 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.
The chip includes an Enhanced DES accelerator which is accessible via cryptographic software libraries located in ST ROM.
The chip includes a Modular Arithmetic Processor (MAP) based on a 1088-bit processor architecture. It processes modular multiplication, squaring and additional operand calculations up to 2176 bits.
The Internal MAP and Enhanced DES accelerator are designed to speed up cryptographic calculations using Public Key Algorithms and Secret Key Algorithms.
As with the other ST19N products, two serial interfaces compatible with the ISO 7816 standard are available.
A CRC calculation block is also available and is directly accessible by the User.
