Nice one.
New 8-bit PIC having 8051 instruction sets :-)
http://www.microchip.com/wwwproducts/Devices.aspx?dDocName=en549565

"Home  -> Products ->   8-bit PIC® Microcontrollers
The SST89V516RD2 is a member of the FlashFlex family of 8-bit
microcontroller products designed and manufactured with patented and
proprietary SuperFlash CMOS semiconductor process technology.
The split-gate cell design and thick-oxide tunneling injector offer
significant cost and reliability benefits for SST customers. It uses
the 8051 instruction set and is pin-for-pin compatible with standard
8051 microcontroller devices."

Hmm, interesting.

Searching for SST shows that Microchip acquired SST a year ago:

In MAPS I can see some SST devices in the list but it does not show any
details, only that can access to some basic PDF files with the device
family.

It's not a PIC.

Flash based 8051s around somewhile. There is one on the desk behind me with a serial bootloader.

Actually to my mind only 10, 12, 16 and 18 types are really PICs.

The higher end chips from Microchip are higher end MPUs. Not same architecture or Instruction set.

Surely the Instruction set and to extent the Architecture decides the Family. I think it's a bit silly the way Microchip calls everything including their MIPS based chip a "PIC".

Yes, I would hesitate to call those devices a PIC, seeing they are made by an acquired subsidiary, but I guess if they come out with the microchip brand on them, then they do get called PIC ...
