GENERAL DESCRIPTION
The PCB2032 contains a 256 x 8-bit EEPROM with
programmable write protection for each of the first 32
bytes. Reading of the whole memory is always possible.
The memory can be written and erased byte by byte.
Each of the first 32 bytes can be write/erase protected by
setting a Protection bit (EEPROM converted to ROM). If
set once, the Protection bit cannot be erased.
Additionally, the PCB2032 allows for a verification
procedure. The whole memory can be read always.
