Re: BTC 0197 - Datasheet

I'm looking to extend the led backlight timing, I'll try on my own, if I'm not successful you might see me back looking for assistance in that one as well.
Cheers!

brymen make meters for other brands.

It's actually in a Greenlee multimeter, I'm not sure who 'copied'who, or if it's just mass branded, but nothing in this meter is labeled Bryman, everything is labeled "Greenlee" or similar.

Thank you for the help, I'll look into that and see if that information proves fruitful.

It is a custom IC for Brymen. 8-bit MCU, LCD controller... likely just like a Hycon HY17P68 but with some modified features. I'd expect a few pins or die flip/rotate to get the pinout to match.
I think the DMM section is not used and instead the second big IC BTC AD-85-4 is the DMM A/D portion.

Hello,

I'm looking for a datasheet for a display controller. Any searches I make for BTC just result in Bitcoin results, In not sure who the manufacturer is to search their full name. Please see the image of the IC.

Thank you for your time.

Is it in a Brymen multimeter
