DSP, Micros & Memory
Atmel's AT90SC320856 is the latest in its market-leading AT90SC family of AVR-based secure flash microcontrollers for smartcards. It offers a range of features that are ideally suited for GSM SIM cards and 3G USIM cards, and also works well for other applications such as Pay TV and government applications. According to the company the secure microcontroller provides customers with unique flexibility since it is the only product of its type to offer a combination of on board ROM, flash and EEPROM memory.
In the AT90SC320856, 32 KB ROM is used to store the fixed part of the operating system, 8 KB flash is used to store the customised parts of the OS where applications are stored or patches to the main OS in ROM are made, and 56 KB of EEPROM is used for data and applications.
