Erasing LPC1833 internal EEPROM

Hello,

I am using the LPC1833 and the internal EEPROM. I'm not understand,does EEPROM erase, when erasing Flash with programmer, or the only way to use erasing from my code? It's generally a part of Flash memory or not?

Best regards

It really depends on the Flash programmer. Fundamentally, Flash and EEPROM are separate peripherals with different programming interfaces. Actions performed to one will have no effect on the other.

LPCScrypt can be used to program and erase EEPROM and also supports an erase all command - this simply calls the erase function of all programmable devices known to LPCScrypt on a particular MCU.

Also LPCOpen provides example code to manage the programming of EEPROMs.

Ok, and if I store important information in EEPROM; Flash protected from reading. Anyone can erase only Flash and write new code for reading EEPROM?

Best regards
