Table 10. Atmel AT88SC25616C User Memory
Note:
Control Logic
Access to the user zones occurs only through the device’s control logic. This logic is configurable through proper
programming of access, passwords and keys registers of the configuration memory during device personalization. This
logic also implements the cryptographic engine for performing the various higher-level security functions of the device.
Configuration Memory
The configuration memory consists of 2048-bits of EEPROM memory used for storing passwords, keys, codes and
defining security levels to be used for each User Zone. The control logic defines access rights to the configuration
memory as well as to the user zones and the user may not alter these rights. The access rights include the ability to
program certain portions of the configuration memory and then lock the data written through the use of Security Fuses.
The configuration memory for each Atmel
Access Registers and Password/Key Registers available. Devices with four user zones have four sets of registers,
those with eight user zones eight sets of registers, and those with 16 user zones 16 sets of registers. Unused memory
space in the register region becomes reserved to ensure other components of the configuration memory remain at the
same address location regardless of the number of user zones in a device.
