2 Circuit Description

The memory is organized in a Main Memory of 256 byte.

Each of the first 32 bytes of the Main Memory can be irreversibly protected against data change by

writing the corresponding bit in the Protection Memory (32 bit). Dependent on the state of the

protection bit the memory is read only (ROM) or may be erased and written again (EEPROM).

Change of the manufacturer code is only possible by the chip manufacturer.

SLE 5542

Change of data of the Main Memory and write a bit of the Protection Memory is only possible after

a correct verification of the Programmable Security Code (PSC).
