The AT88SC1616C provides an ISO 7816-3 compliant asynchronous answer to reset
sequence. When the reset sequence is activated, the device will output the data programmed
into the 64-bit answer to reset register. An internal pull-up on the RST input pad allows the
device to be used in synchronous mode without bonding RST. The AT88SC1616C does not
support the synchronous answer to reset sequence.
The EEPROM user memory is divided into 16 zones of 1024 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 the user during the personalization of the device in the configuration zone. If the
same security requirements are selected for multiple zones, then these zones may effectively
be accessed as one larger zone.
Table 2. User Zones
Access to the user zones occurs only through the control logic built into the device. This logic
is configurable through access registers, key registers and keys programmed into the configu-
ration zone during device personalization. Also implemented in the control logic is a
cryptographic engine for performing the various higher level security functions of the device.
