FPGA and sNVM Locks

User security locks prevent erasing and overwriting user-defined bitstream encryption keys and user security segments. When defining your own bitstream encryption key, these locks get set automatically.

Debug locks can disable aspects of the SmartDebug system, the JTAG boundary scan functionality, reading of sensors over the JTAG/SPI interfaces and custom JTAG commands through the JTAG interface.

You can permanently disable or alternatively enable factory test modes with a user pass code. If permanently disabled, we will be unable to perform any failure analysis on the device.

You can use permanent locks to effectively create a One-Time Programmable (OTP) or ASIC-like device with no future update capabilities, factory access or debug capabilities.

Programming locks will disable the JTAG and SPI slave programming interfaces as well as auto-programming or in-application programming services.
