Onsemi AR1335 CMOS image sensor pinout
« on: May 07, 2024, 05:28:36 am »
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.

Not sure how long it'll last, but google found this:
https://community.nxp.com/pwmxy87654/attachments/pwmxy87654/imxrt/13464/2/AR1335-D(1).pdf
Which, upon closer inspection, seems to contain anything but the pinout? Contains a nice pic of the BGA package, though  :palm:

Can't tell how many times I downloaded this exact document :-DD Got exited once I saw the footprint but got frustrated again once I saw (or not saw) the ball names... At this point, I also found a reference design with a symbol, but the symbol only matches the wire-bond version of the AR1335 and does not match ball name nor the number of pads (58 instead of 63 If I remember correctly).

It's quite ironic how all the confidential information is splattered across the web, but the non-critical information a potential customer would need is not accessible - not even if you ask  :horse:

It is hilarious   :palm: and under normal circumstances I would probably just bugger off, telling them to go f themselves, but there simply is no substitute matching the requirements...

I appreciate your effort and I actually did not find this document in my research. However, the Pinout present seems to belong to some kind of obsolete packaging (CLCC48) made when onsemi was still ON semiconductor... There is nothing to be found on the AR1335HS even on onsemi's official (yet shitty) website, so I do not think that part is in production anymore. |O

I am looking for the pinout of the BGA package (ODCSP-63)
