3.3
The Flash memory provides an embedded user-programmable non-volatile memory,
allowing fast and reliable storage of user code and data. It is operated from a single 2.5 V
supply from the Embedded Voltage Regulator (EVR) and does not require additional
programming or erasing voltage. The sectorization of the Flash memory allows each
sector to be erased independently.
