Is it possible to erase Full chip?

Hello, I have a question:

Is it possible to erase full chip (for example... erase full chip after counter value get value 100)?

I'm using stm32f303cb.

Thank you for your time,

What counter? Do you mean, can the chip erase itself? Have you read the FLASH chapter in manual?

I understand the question to mean that you want to delete the flash when a counter reaches a certain value, right?

This is possible by moving the erase routine to RAM and starting it there, but the power supply could fail during the erase process, which might not completely erase the flash.

Read the FLASH chapter in RM I referenced to above, it contains all the information you need.
