The sanction was imposed by an independent regulatory commission after Pardew had admitted a misconduct charge, the Football Association announced.
He was also fined £60,000 and warned as to his future conduct after the incident during Newcastle's 4-1 win at Hull on March 1.
A statement from the FA read: "Newcastle United manager Alan Pardew will serve a seven-match suspension with immediate effect, subject to any appeal, after he admitted an FA misconduct charge.
"An independent regulatory commission today [Tuesday 11 March 2014] ruled the first three matches imposed are a stadium ban with the remaining four a touchline ban."
Pardew, who has also been fined £100,000 and given a formal warning by his club, said he will accept the latest punishment.
The Newcastle manager said in a statement released by his club: "As I have made clear, I deeply regret the incident and again wholeheartedly apologise to all parties for my conduct, which I understand was not acceptable.
"I will accept the punishment handed down by the FA today. My focus now turns to preparing the team for this weekend's game against Fulham and finishing the season as strongly as possible."
