Secured Microcontroller Memory Breaking is also called MCU cracking, which used technical methods to compromise the protective mechanism of microprocessor and extract embedded firmware from its flash or eeprom memory, but they have become customary names.

We are used to calling CPLD eprom memory breaking and DSP microcontroller program/data recovery as Secured Microcontroller Memory Breaking. The single chip microcomputer is only one of the classes that can load the program chip.

There are DSP, CPLD, PLD, AVR, ARM, etc. chips that can download programs and can encrypt. Of course, memory chips with storage functions can also be encrypted, such as DS2401, DS2501, AT88S0104, DM2602, AT88SC0104D, etc.

There are also chips specifically designed with encryption algorithms for professional encryption or functional chips such as design verification manufacturers’ code work. This type of chip industry can prevent Purpose of product reproduction.
