using something like the 'brownout detector' power controller above. I'm pretty sure I've seen designs (and done this myself), that just puts a little RC on the reset pin. 100ms aughta be enough for anyone! microcontrollers (like those used for board controllers) have a much simpler power and clock structure than big cpus...and many of them are built to just come up on their own.

- convolvatron 4y agointernal flash for boot, internal power control, internal clock
- MichaelZuo 4y agoIt sounds a bit recursive, wouldn't the internal boot process need the same sort of procedure?
- convolvatron 4y agoI just was looking at https://www.pjrc.com/store/ic_mkl02_t4.html https://www.pjrc.com/store/ic_mkl02_t4.html maybe this will give you some context, its about a small controller booting a larger SOC ARM part
