LPC54605J256BD100 microcontroller EEPROM Specification

Hi,

In LPC546xx datasheet, it is mentioned that upto 16 KB EEPROM is available but i couldn't find the exact details of the parts containing the EEPROM. I want to know whether LPC54605J256BD100 has EEPROM and if yes then please mention the size of EEPROM as well. Also, if LPC54605J256BD100 doesn't contain EEPROM then please suggest any alternative part with 256KB flash,136 KB ram in LQFP package from LPC546xx family with EEPROM.

Thanks and best regards,

Prasanna

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

Thanks Sol. Do you have any document mentioning the size?

Best regards,
