That is the microcontroller chip so if that failed the unit probably wouldn’t work at all. It could theoretically be replaced but it may have been customized for Delonghi. The part number for the whole board is 5232120900. I’d contact Delonghi to see if it’s available. Their parts site says it’s “not available for resale”.
