I am developing a PCB that embeds a CX3. Both memories which are in e-Con DENEBOLA CX3 RDK Schematics are the following:

I2C EEPROM ->  model  AT24C1024B-TH-B   from  Microchip Technology.

SPI FLASH    ->  model  M25P40-VMN6TPB  from Micron Technology.

The problem is that both memories are not available, so, it is possible to know if there are any others which can work with the CX3, and of course with the same characteristics?

Thanks so much.

Hi,

Please kindly refer to this KBA for flash selection:

You can also refer to AN76405 https://www.cypress.com/file/201991/download  for the selection of EEPROM and flash.

Hi, thanks so much.

I guess it is not necessary to add both memories on the PCB. I mean, why is it necessary to have two non-volatile memories to store the CX3 image?

Or is it completely necessary to have both in order to get a good behaviour of the CX3?

Thanks.

Hi,

Either one of them is applicable. You just need one place to store your firmware.
