content: No one is going to watch 34 minutes of video for an "identify this IC" request...Since the OP so very helpfully decided to edit out the picture of the IC he was asking to identify, I'll post it in text formfor future seekers: EF52AXWMN101EF52A? Otherwise it's probably an 8051, as "52A" sounds vaguely familiar but I can't remember the exact company that made such a series.

content: Google just the first half of that number. EF52AXW. You'll get results. A lot of different, unrelated ones, but maybe one is good. I don't know, I didn't take the time to look through them :p

content: You say ripoff? IMO your conclusion is sucked it out of thumb. So what that it flashes when you connect certain pins together. It's internals are way too expensive to be just a blinker.Form your youtube comment:QuoteHave nothing other to say than

content: Quote from: wraper on August 27, 2016, 08:06:13 pmOK, So everyone's getting a laugh, that's cool. Still, WTF is this chip? Oh, and if you watch the video in it's full context, you'll see I'm thinking out-loud. Also, I NEVER admit to knowing what this chip is, nor how the circuit works. So, If you're so much smarter than me, explain what this chip is, and what this circuit might be doing...It's so easy to make fun, slap your hand to your face, and let everyone know what an idiot I am. Job well done!For the rest of you who want to take a jab at me, it doesn't matter, knock yourselves out!

content: It's almost certainly an 8 bit microcontroller. The PCB even has the JTAG programming socket pads next to it.

content: Quote from: KentuckyOutback on August 27, 2016, 08:42:51 pmas amyk said, very likely it's MN101EF52A MCU. It's available in 32-Pin TQFP (7 mm x 7 mm / 0.8mm pitch) package as on your video.http://www.semicon.panasonic.co.jp/ds4/MN101E51__E.pdfQuotePreview of your video shows "DEBUNKED", while actually it is either faulty, incompatible with particular cartridges, or protection in cartridges was updated so device cannot reset newer revision of them.

content: Not all cartridge resetters are compatible with all cartridges, and some may not even be resettable because they use OTP or similar, but they are not a "scam". I recommend the OP start his research here:http://www.eddiem.com/photo/CIS/inkchip/chip.html

content: Do the pins pogo? If not, there could be difficulties maintaining contact, and could be a reason it doesn't work. The other reason, obviously, is the EEPROM in the cartridge has a different interface. And, of course, it could simply be defective or ESD damaged.As for the chip, of course it's a dirt cheap microcontroller of some variety with a bitbang GPIO interface and 100 bytes of code. It's the only design that makes sense here. As long as it's compatible with the cartridge interface and the pins can reliably maintain contact it's super simple to make this work. A first-year EE student could put one together as a school project without difficulty.I actually find it kind of rude to insinuate Chinese engineers can't design an EEPROM wiper. Get real.
