Memories
1.6.1
Embedded Flash memory
The embedded Flash has the following features:
640 kB or 1 MB of size
128-bit wide data read
64-bit data write through a double 32-bit bus write
Sector erase with possibility to suspend erase procedure in case of read access to
other flash sectors
Multiple sector erase.
Shadow sector is accessible only in some security levels (see Section 1.12: Boot modes on
page 28).
1.6.2
One-time programmable (OTP) section
The STCOM embeds a one-time programmable (OTP) section in the shadow sector of the
embedded Flash memory. During the manufacturing process, the EUI48 is stored in this
section. The user can also write its private key used during the boot process to verify and
authenticate the firmware image. This OTP section can be configured to avoid reads by
firmware in order to protect user confidential information (see Section 1.12).
