I am currently working on a CCTV project which utilizes the Onsemi (Former ON Semiconductor) AR1335 (AR1335CSSC11SMKA0-CP2) for its high image quality, available drivers and configs + BGA package (no wire bonding rubbish).
I spent 3 days looking for an available pinout on the BGA package without success. I also contacted Onsemi for support but did not even get a message received mail back…
I mean i get that manufacturers may want to keep sensitive information behind a paywall or NDA, but why the hell a PINOUT???
You can purchase the part through Mouser, Digikey, Farnell and even LCSC in quantities of > 1000pcs, but cannot do anything with them without the pinout. WTF?
So, to get to my question(s):
Can somebody explain, why an IC manufacturer might keep the IC-Pinout secret? Any secret sauce in it? I mean the footprint is available but no references from Ball name to pin name…
Does anyone have a source for the pinout of the part? I do NOT need the entire datasheet since all the heavy lifting of sensor integration for my platform (NXP i.MX8MP) is already dealt with by NXP. I only need the pinout.
I apologise for possible bad writing, as i am really writing in anger right now. Still, i hope you guys might be able to help.
