2 Circuit Description

Memory Organization

The memory is organized in a Data Memory of 1024 byte.

Write and Read-Out 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.

• Read-Out Protection Bits: Three sectors of the Data Memory can be irreversibly protected

against read-out by writing the corresponding bit in the Read Protection Memory.

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).

• Read-out of read-protected Data Memory sector only after verification of the 2-Byte

Programmable Security Code (PSC).
