大容量內(nèi)存智能卡芯片

產(chǎn)品詳情：

A系列

A系列使用新開發(fā)的非揮發(fā)性記憶體(Non-volatile memory - NVM)，使在增強(qiáng)讀寫表現(xiàn)的同時提供更佳的性價比。

全線A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。

A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，確保芯片上各個應(yīng)用能使用的資源得妥善的管理而不失安全性。

A系列帶來以下便利：

使用新的NVM提高性價比
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)省個人化時間
低功耗 - 更長的電池壽命
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
安全功能 - 可將未經(jīng)授權(quán)訪問卡內(nèi)數(shù)據(jù)的風(fēng)險降到最低

uT83SCA1XY

SmartCard MCU with 100-160KB FLASH and High Speed I/O

The uT83SCA1XY is a contact mode smart card MCU, which complies with ISO7816 standard. It is targetting for high end GSM SIM Card applications and smart card applications require a large NVM.

uT83SCA1XY is a member of the A-series family, which is using advance NVM technology to meet customers’ need. It has an internal NVM that can be user configurable into program and data storage areas. The NVM area configured for user program
can be protected from accidental changes, making it similar to a typical mask ROM. The buit-in Memory Management Unit (MMU) together with firewall feature makes uT83SCA1XY suitable for multi-application environment.

Built-in memory size of each device are listed in table below:

Part No. NVM RAM
XY=60 uT83SCA160 160KB 4KB
XY=48 uT83SCA148 148KB 3KB
XY=30 uT83SCA130 130KB 3KB
XY=20 uT83SCA120 120KB 3KB
XY=00 uT83SCA100 100KB 3KB
