T93 TCM insides
T93 TCM insides
Curiosity got the best of me today so I popped off the cover from one of the t93 TCMs I have laying around. I thought maybe some here would be interested as well.

All those lead frame chips are crazy.

That's nuts.
Re: T93 TCM insides
I'm trying to figure out what this processor is. spc574 of some sort maybe?

Re: T93 TCM insides
This is a long shot, but I've seen a few utility files and binaries that have a short ASCII string that identifies the CPU or at least the flash memory type.
As much as it scars my soul to post anything from TikTok, this says it's an SPC5888.

Good find, now that you've posted that I searched SPC5888 T93 and there are enough hits that it seems likely.
Have you read the FAQ? For lots of information and links to significant threads see here: http://pcmhacking.net/forums/viewtopic.php?f=7&t=1396
Re: T93 TCM insides
yeah looks to be the case. I wasn't able to find a reference manual for the spc5888 but the SPC58 C Line manual seems to match up to the addressing well.

Re: T93 TCM insides
I did some checking myself. "5888" doesn't seem to be a thing. But I can't find anything else that's even close. They don't list a bare die package in the catalog at all. It's probably some custom order bullshit.
Re: T93 TCM insides
The closest manual I see that matches the memory layout is the SPC58 E/G Line
