Embedded Flash memory

The devices feature up to 1 Mbyte of embedded Flash memory which is available for storing

programs and data.

The Flash interface features:

–

Single or dual bank operating modes

–

Read-while-write (RWW) in dual bank mode

This feature allows to perform a read operation from one bank while an erase or program

operation is performed to the other bank. The dual-bank boot is also supported. Each bank

contains 128 pages of 4 Kbytes. In Single-bank mode the main Flash memory contains 128

pages of 8 Kbytes.

Flexible protections can be configured thanks to the option bytes:

• Readout protection (RDP) to protect the whole memory. Three levels of protection are

available:

– Level 0: no readout protection

– Level 1: memory readout protection; the Flash memory cannot be read from or written

to if either the debug features are connected or the boot in RAM or bootloader are

selected

– Level 2: chip readout protection; the debug features (Cortex-M4 JTAG and serial

wire), the boot in RAM and the bootloader selection are disabled (JTAG fuse). This

selection is irreversible.
