The possible longest length of single vcc glitch

HI,I do the research about the vcc glitch’s effect on the True Random Number Generator.
The device I use are CW305 and CW-lite(2 part).
After I set the length of glitch to be about 2us, the CW305 would “reset”(Just like push the “USB RST” button).
WHY? Does the CW305 can afford the powerful fault?

Thank a lot.

Are you able to observe any fault on the power rail for the Sam3U?


Hi, @Alex_Dewar,the LEDs near the SAM3U actually flash on the condition above.
