Has anyone had any luck reading or writing to this device? It's not in the device list but maybe another number is the same? It's a Philips (NXP) MCU with only 24 pins. It's based on 80C51 architecture. Any help would be appreciated, I'm even open to paying someone to develop the profile to make the 4X4 work on this IC, Not a lot or I'd just buy one of the more expensive programmers but definitely some beer and pizza money. I can send samples.

I know this is several years old, but did you ever find a solution for reading off this IC? I am trying to revive an older piece of audio gear that uses this chip for the front panel controls.

no. no luck at all. It needs too much power.
