I will speculate that this is some kind of a microcontroller. Which one? Can you post a copy of the Data Sheet? (No, I am NOT inclined to wade through a manufacturer’s web pages, loaded with advertising and pop-ups, to find the Date Sheet for a part in YOUR design project.)
Did you notice that those capacitors have different values? There are three, 100 nF (0.1 uF); one, 10 nF (0.01 uF); two, 10 uF; and two, 22 uF. Now, 0.1 uF is probably the “standard” value for power supply decoupling (and is currently experiencing a supply shortage). Manufacturers typically advise us to locate these “as close as possible” to supply pins.
0.01 uF (10 nF) is much less common. That value might be used on a supply pin dedicated to some special function - perhaps the A/D converter’s supply pin, or an analog signal conditioning block, or a high-speed line transceiver, etc. Something that is either especially sensitive to power supply noise, or something that is inclined to corrupt a supply rail with noise.
Manufacturers will sometimes call for bulk filtering capacitors, in the range of 10 uF to 100 uF or so, on a one-per-board basis. Usually they are specified as “good-quality tantalum or aluminum electrolytic” components, rather than ceramic capacitors. The 10 uF and 22 uF parts seem to fit this bill, though I don’t understand why there are two of each value.
I’ll also mention that the note on your schematic snippet, “Note: Place close to CPU power pin.” is a little ambiguous. Does it only apply to the three capacitors immediately adjacent to it, or to all eight? The white space between C808 and C810 on the drawing suggests that the Note applies to only C806, C807, and C808.
I suggest you spend some time carefully reading the Data Sheet. You may find the information you are looking for in a section called “Power Supply”, or “Layout Considerations”. It may be buried in a footnote with tiny print. Or, if the manufacturer has published “Application Notes” or “Reference Designs” for this part, they may contain more complete discussions of the power supply decoupling requirements.
