Datasheets 6530
The 6530 was produced by most licensed 6502 manufacturers, from MOS Technology/Commodore SG to Rockwell and Synertek. All production datasheets that I have seen are identical
The oldest one is a preliminary MOS datasheet for the MCS6530, missing the ordering pages of the production version.
The most complete datasheet of the 6530 are the Synertek and Rockwell versiona, first in next table.
6532
CMOS 6532
The 6532 exists in CMOS variants, I have only seen the California Micro Devices GTE 65SC32 variant.

Other RIOTs
In Rockwell databooks there are more RIOTs described. 6531, 6534. Never seen in the wild, a mention here and there of being used in pinball machines.
The timer/counter is a lot more capable, 16 bits etc.
