built in microwave outlet

[brosnt1]

If you install a built in microwave with the outlet inside the cabinet, can this outlet be part of one of the 2-20 amp convenience outlets, or do you have to run a dedicated circuit, also what is the amperage for a microwave 15 or 20? what is the amperage for an electric range?
any information will be greatly appreciated.
Thanks

That microwave must have a dedicated 20A circuit.

Most ranges have a 50A circuit.
