I don't need a data book for that one :-) It's the base member of the
Intel 8051 family, also known as the MCS-51 family, which is an
enhanced version of the 8048 family of microcontrollers. IIRC it has
some extra instructions and addressing modes.
The 8031 is the version without on-board ROM. Philips was one of
several second-sources for it.
