Clarification on On-Chip Memory for LPC54018J2MET180

Hi,

I am reviewing the LPC54018J2MET180 microcontroller and noticed that the datasheet and system architecture mention 2MB or 4MB on-chip memory, but this detail is not included in the user manual.

Please confirm the exact on-chip memory size for this part number. Also, is there any special or updated user manual available for this product?

Looking forward to your response.

Hello @Alice_Yang ,
Thanks for the update. Do you have a user manual that includes on-chip memory details? We need it for software analysis.
