Reference design for Padauk MCUs
« on: January 04, 2019, 01:29:19 pm »
There's a great discussion going on reverse engineering the programmer for Padauk's microcontrollers. The folks there are making a very impressive progress and I do not wish to interfere in that discussion. So, I'm posting this question separetely.

I'm intrigued by the flash products, more specifically, the PFS154 and the PFS173.

Does anyone have a schematic for these two in particular or any other of Padauk's MCUs? For the life of me, I'm unable to find anything and I'd like to see how others have sized the power supply bypass caps, protected the power input (which needs to go up to 8V for programming), shared the programming pins with other peripherals, und so weiter.

I've made a board that supports the PFS154 and the PFS173:

I've run some C programs (written in C) on them, in particular the LED timer count example (https://github.com/free-pdk/sdcc-pdk-code-examples).
