Circuit Description
Memory Organization
The memory is organized in a Data Memory of 1024 byte.
Write Protection of Data Memory
Write Protection Bits: Each byte of the Data Memory can be irreversibly protected against data
change by writing the corresponding bit in the Write Protection Memory. Dependent on the state
of the protection bit the Data Memory is read only (ROM) or may be erased and written again
(EEPROM). The manufacturer code (Application ID and Chip Coding) is programmed unalterable
by the chip manufacturer.
Programmable Security Code
Altering data in the Data Memory as well as setting a Write Protection Bit is only possible after
verification of the 2-Byte Programmable Security Code (PSC).
