Narrative:

At FL330 we experienced multiple failures of system associated with bus #2; including both first officer's pfd and nd; ECAM sd; both engine EPR modes; autothrottles; bscu #2; eis dmc #2; fuel pump #2 left tank; fuel pump #2 center tank; to mention a few. I also noted the smell of smoke. We elected to don our oxygen masks. Since we were 180 NM southwest of ZZZ (ZZZ WX was VFR) we declared an emergency and diverted in. I briefed the flight attendants and told them to do a cabin advisory. I also asked them to check for smoke. They did and said they did not smell any. We gave the passenger a quick briefing and our ETA to ZZZ. We ran all ECAM checklists and did and overweight landing checklist. We landed at 157000 pounds with less than a 200 FPM rate of descent with a soft touchdown. After landing the crash fire rescue crew did a visual inspection and noted no smoke or other damage. We then taxied to the gate. After shutdown; further inspection revealed that circuit breaker AB2 on the 123VU panel was tripped and the head was missing.
