產(chǎn)品詳情：

NC系列

NC系列產(chǎn)品是針對(duì)保密性和安全性要求非常高的應(yīng)用而設(shè)計(jì)的。NC系列產(chǎn)品均內(nèi)置2048-bit加密處理器和3DES處理器。能實(shí)現(xiàn)各種公開密鑰(例如RSA)等算法。

全線NC系列芯片不使用硬掩膜，用戶可在最後一刻才把COS下載到芯片上。使用上更靈活，存貨易於管理。

NC系列產(chǎn)品亦內(nèi)置記憶體管理單元(MMU)，加上防火墻的功能，使得這系列產(chǎn)品特別適合一卡多用的情況，確保芯片上各個(gè)應(yīng)用能使用的資源得妥善的管理而不失安全性。

NC系列帶來以下便利：

靈活 - 客戶可以按照具體的需要將NVM劃分為代碼區(qū)和數(shù)據(jù)區(qū)
縮短生產(chǎn)周期 - 無需硬掩膜
高速處理可節(jié)省個(gè)人化時(shí)間
低功耗 - 更長(zhǎng)的電池壽命
內(nèi)置記憶體管理和防火墻 - 支持總管和用戶模式，方便多一卡多用
保密功能 - 內(nèi)置2048位加密處理器
安全功能 - 可將未經(jīng)授權(quán)訪問卡內(nèi)數(shù)據(jù)的風(fēng)險(xiǎn)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.
