TMS570LS3137: How to protect the Flash ROM binary code from being pirated

Chuck Wong

Part Number: TMS570LS3137

Hello there,

Is there any MCU-integrated protection function that could prevent the Flash binary code from being copied by external tools?

If so, could you please point me to the topics?

Thank you!

Does the Advanced JTAG Security Module section in the TMS570LS3137 16- and 32-Bit RISC Flash Microcontroller datasheet (Rev. C) answer your question?

Hi Chuck,

As Chester said, this device has AJSM module which can be used to protect the flash. Please refer to this app note for generating lock key and unlock key.
