AT88SC0808C

grammed 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

AT88SC0808C does not support the synchronous answer-to-reset sequence.

Device Architecture

User Zones

The EEPROM user memory is divided into 8 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 con-

figuration zone. If the same security requirements are selected for multiple zones, then

these zones may effectively be accessed as one larger zone.

Control Logic

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 configuration 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.
