A potentially big trap for young and old players alike. This is not something you'd normally get taught. Can you guess how it's done before the secret is revealed? Forum: http://www.eevblog.com/forum/blog/eevblog-831-power-a-micro-with-no-power-pin!/ SPOILER: A tutorial on how ESD protection diodes in chips work and how they can be used, mostly inadvertently to power a chip through the input and output pins without having the power or ground pin connected. This example uses an MSP430 microcontroller, but is applicable to almost any complex or simple CMOS chip.
