Members of the M•CORE microcontroller family with the SGFM (second
generation FLASH for M•CORE) module incorporate features that
prevent unauthorized users from reading the contents of the SGFM
array.
The security mechanism comprises several hardware interlocks that
block the means by which an unauthorized user could gain access to the
FLASH array. Apart from dedicated non-volatile memory bits in the
SGFM array that engage security, the interlocking mechanism consists
exclusively of digital logic constructs that require no special processing.
Thorough MCU security must incorporate both hardware and software
considerations. While the MMC2113 and MMC2114 provide the
necessary hardware interlocks, it is incumbent upon the user to write
software that minimizes the potential for unauthorized code and data
access. In particular, if firmware-based debug, diagnostic, or update
interfaces are needed, they should be protected with passwords that are
not easily compromised. Even brute force hacking attempts can be foiled
by incorporating exponential time delays after failed password entries.
When used together, the FLASH back door security key and an
appropriately defined software construct can provide both password
protection and product identification or serialization features.
