... Description The AT88SC12816C member of the CryptoMemory of user memory with advanced security and cryptographic features built in. The user memory is divided into 16 1-Kbyte zones, each of which may be individually set with different security access rights or effectively combined together to provide space for one to sixteen data files. ...

... User Zones The EEPROM user memory is divided into 16 zones of 8,192 bits each. Multiple zones allow for different types of data or files to be stored in different zones. Access to the user zones is allowed only after security requirements have been met. These security requirements are defined by theuser during the personalization of the device in the configuration memory ...
Page 10
... The configuration memory consists of 2048 bits of EEPROM memory used for storing passwords, keys and codes and for defining security levels to be used for each user zone. Access rights to the configuration memory are defined in the control logic and may not be altered by the user. ...

... Provide a clock signal to CLK-SCL. • RST goes high after 400 clock cycles. The device will respond with a 64-bit ATR code, including historical bytes to indicate the memory density within the CryptoMemory family. Once the asynchronous mode has been selected not possible to switch to the synchronous mode without powering off the device ...
