Is it possible to emulate EEPROM using the P-flash of KE microcontroller?

[simonefantuzzi]

I see the microcontroller KE we have choose doesn't have EEPROM.

Is it possible to emulate it using a part of the 8kb flash?

Flex memory is not mentioned on the KE data sheet.

Thank you very much

Hello Simone:

You may take a look to the application note "AN4903 EEPROM Emulation Driver for the Kinetis E Series Microcontrollers":

http://cache.freescale.com/files/microcontrollers/doc/app_note/AN4903.pdf

The appnote comes with a software package. To download it run a search in Freescale webpage for AN4903 and you will find it as a ZIP file:

Hi Jorge,

I want to use the flash as an EEPROM with MKE04 and I am interested in AN4903SW driver, which I can't found it. Please, can you send me the dowload link or zip?

Thanks.

Joaquim.

Hi Simone

I think that the following thread has the answer to your question:

Of course the 8k Flash is quite small but it is still possible to use a 512 byte sector to save parameters in (even if not pure EEPROM).
