Strange chip

[Fernando Pena López]

Hi all...

I need some help to identify an strange chip...
I know that this chip is an arm mcu, but I need to get its datasheet.
The chip say on its surface:

VLSI-ARM (1st line)
9643 B791951 (2nd line... and so go on...)
VP40518-
VP22002

I belive that it's an arm 710 mcu...
Can anybody help me?

Thanks in advance.

Fernando Pena López.

What's it out of? A PDA? It's probably a custom part. VLSI made loads of
mfr-specific parts.
