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 of PCB2032 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.
