Iyer's 11th first-class ton and his 187-run partnership with opener Akhil Herwadkar, who made 132, saw Mumbai make 371 for 5 before declaring in the second innings after conceding a 76-run lead to the visitors.
Tamil Nadu had posted 450 in reply to Mumbai's first innings total of 374.
The game ended with Mumbai's declaration.
Tamil Nadu got three points while the home side had to settle for one.
Having conceded the lead, Mumbai had an uphill task at hand to force the pace and go for a result and Iyer's splendid ton provided the impetus, but it wasn't enough.
The 22-year-old right-hander reached his ton off 100 balls while Herwadkar proved to be the ideal foil as he rotated the strike efficiently.
Herwadkar took over after the fall of Iyer and reached his century as the home team frustrated Tamil Nadu bowlers. He was dismissed by Rahil Shah for 132 and his innings included 14 fours and three sixers.
It was a tough day for the Tamil Nadu bowlers with only left-arm spinner Shah and Vignesh finding success. The country's premier off-spinner Ravichandran Ashwin went wicketless in the 26 overs he bowled, conceding 110 runs.
Tamil Nadu batsman B Indrajith was named player of the match for the knock of 152.
Tamil Nadu has seven points from three games while Mumbai has four after two matches.
Mumbai's next match is against Odisha at Bhubaneshwar from November 1 while Tamil Nadu would meet Odisha at Cuttack from November 9.
At Vizianagaram: Andhra Pradesh 584 for 4 declared in 166 overs (G Hanuma Vihari 302 not out) vs Odisha 391 all out in 139.3 overs (Govinda Poddar 111, Subhransu Senapati 91, Bhargav Bhatt 4 for 77) and 152 for 7 in 55 overs (Biplad Samantaray 62 not out, Bhargav Bhatt 4 for 40). Points: Andhra Pradesh: 3; Odisha: 1.
