Does kitchen microwave not microwave oven require dedicated receptacle or can the microwave receptacle be part of parallel receptacles branch circuit? Where in code?

Are you talking over the range or one sitting on the counter? It does not require a separate circuit if the microwave is fixed in place and isn't more than 50% of the branch circuit rating of 20 amps. Practically this means a microwave needs a separate circuit.

Over the range like in dewelling unit kitchen. Where in code it says all that?

You need also follow the mfg instructions. Most I have seen require a separate circuit.
A 1000w Micro has a input of about 1500w

Look at 220.23

If it's going over the stove/range then it needs a separate circuit. The code says for "hood" and since the MW is there it needs it. Also the MW has an exhaust fan built in.

The issue really is the what the manufacture says and also if its rated over 50% of the branch circuit. How many code sections does one need to say " separate or dedicated circuit "

There is no way around it unless its a free standing unit.

Need to have some type of hood over a range. If gas it needs to exhausted to the outside. Not a NEC thing but a Building code thing.
Why would one install a range and no hood or downdraft:?

Again if it is built in it needs a dedicated circuit. If on a shelf free standing then no.

Range hood/micro combo are typically cord and plug connected and therefore require an individual branch circuit.

(4) Range Hoods. Range hoods shall be permitted to be
cord-and-plug-connected with a flexible cord identified as
suitable for use on range hoods in the installation instruc-
tions of the appliance manufacturer, where all of the fol-
lowing conditions are met:
(1) The flexible cord is terminated with a grounding-type
attachment plug.
Exception: A listed range hood distinctly marked to iden-
tify it as protected by a system of double insulation, or its
equivalent, shall not be required to be terminated with a
grounding-type attachment plug.
(2) The length of the cord is not less than 450 mm (18 in.)
and not over 900 mm (36 in.).
(3) Receptacles are located to avoid physical damage to the
flexible cord.
(4) The receptacle is accessible.
(5) The receptacle is supplied by an individual branch
circuit.

Yes , several code sections point to the same requirement.
Individual branch circuit.

I still have no idea what the OP is calling a microwave. They stated its not an oven and its not a hood.
