NC系列
NC系列产品是针对保密性和安全性要求非常高的应用而设计的。NC系列产品均内置2048-bit加密处理器和3DES处理器。能实现各种公开密钥(例如RSA)等算法。
全线NC系列芯片不使用硬掩膜，用户可在最後一刻才把COS下载到芯片上。使用上更灵活，存货易於管理。
NC系列产品亦内置记忆体管理单元(MMU)，加上防火墙的功能，使得这系列产品特别适合一卡多用的情况，确保芯片上各个应用能使用的资源得妥善的管理而不失安全性。
NC系列带来以下便利：
灵活 - 客户可以按照具体的需要将NVM划分为代码区和数据区
缩短生产周期 - 无需硬掩膜
高速处理可节省个人化时间
低功耗 - 更长的电池寿命
内置记忆体管理和防火墙 - 支持总管和用户模式，方便多一卡多用
保密功能 - 内置2048位加密处理器
安全功能 - 可将未经授权访问卡内数据的风险降到最低
uT83NC128
ROM-less 8-Bit SmartCard MCU with 128KB EEPROM and 2048-bit MAP Processor
uT83NC128 is a contact mode smart card MCU, which complies with ISO7816 standard. It is targetting for very high security applications such as Identity Card, E-commerce and Document Digital Signature. With the built-in crypto co-processor can speed up cryptographic calculation with up to 2048 bits modulo exponetiation (AB mod N) and other similar calculations. uT83NC128 is ideal for applications
require public key encryptions such as RSA.
uT83NC128 features a high performance 8052 CPU which is typically three times faster than standard 8051 CPU. The 128K-byte hybride Non-Volatile-Memory (NVM) which consists of 64KB FLASH and 64KB EEPROM. Program code and data can be located in either FLASH or EEPROM for flexibility.
