DL-0311 / CPS-A-01 Reverse Engineering

[WydD]

Heyo!

I'm very pleased to share to the community my complete reverse-engineering of the CPS-A-01.
I have worked over 8+ months on the die shot of this chip and I've produced the full schematics with a bunch of documentation pages.

Here's the overview image of the schematics


You can access the complete documentation here (and the source code): https://gitlab.com/loic.petit/cps2-reverse/-/tree/master/DLs/DL-0311/
And you can access the online schematics viewer here: https://petitl.fr/cps2/DL-0311/

CPS2 Reverse Engineering Project
This work is part of the more global effort of recreating the schematics of the whole CPS2 including all the custom chips.
Currently you can find complete schematics for the A-board, the B-board, E-board, QSound amplifier, as well as the reverse of the DL-0921 (CPS-B-21), DL-1727, DL-1827, DL-1927 and DL-2027 chips.

I hope you enjoy it!

[EDIT]
83 pages!!!!

You didnt think it would be easy, did you?
The B-21 was 69 pages. This one a tad bigger but I wouldnt say I made it artificially bigger, the chip is just more complex.

That's why I strongly encourage people to use the online explorer I've made https://petitl.fr/cps2/DL-0311/ it is WAY easier to navigate then inside the cumbersome PDF format without links that Kicad generates.
