There are no specific documents on it. It's in the MCS650x data sheet.
It's just a 6502 die in a smaller 28-pin DIP package with not all of the
pins bonded out. Specifically, A12 through A15, RDY, /NMI, SYNC, SO,
three NC pins, and one Vss pin are not available.

The pinout is:

      /RES 1 28 Ph2 out
       Vss 2 27 Ph0 in
    Ph1 out 3 26 R/W
      /IRQ 4 25 D0
       Vcc 5 24 D1
        A0 6 23 D2
        A1 7 22 D3
        A2 8 21 D4
        A3 9 20 D5
        A4 10 19 D6
        A5 11 18 D7
        A6 12 17 A11
        A7 13 16 A10
        A8 14 15 A9


I'm looking for the Synertek 6516 data sheet, and Synertek technical
notes 34 and 40. The 6516 was to be a 16-bit extension of the 6500
family, years before the 65802/65816. Synertek published a data sheet
in mid 1978, but the part was never put into production.
