It doesn't matter what part you want to identify, get the numbers off it and type them into google.
The results will normally tell you.
As for manufacturer, some print their name/logo and some use a number, some chips i have used in the past didn't have anything for the manufacturers code, just a date code.
Physically a microcontroller doesn't look any different to a lot of other chips.
May i suggest in future changing the colour of your text, although I have 20/20 vision my wife does not and couldn't read your post. Black works for most, if you don't like black may i suggest a darker colour.
