Datasheets 6530
The 6530 was produced by most 6502 manufactures, 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.

CMOS 6532
The 6532 exists in CMOS, I have only seen the California Micro Devices GSE 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.
