Hi,
The EEPROM is available on all LPC546xx devices.
The EEPROM can be read and written/erased. A write operation involves two steps. The first step is writing a minimum of 1 word (4 bytes) to a maximum of 32 words (128 bytes) to the desired page in the 16 kB EEPROM address space at address 0x4010 8000. Step two is an erase/program of that page into non-volatile memory. There are 128 pages within the 16 kB EEPROM address space. The last page contains the EEPROM initialization data and is not writable. Note that data written to a page cannot be read back from the page address until the data have been programmed into non-volatile memory.
Have a great day,
Sol
