In context
Usually based on a leadframe, its central exposed pad may provide heat dissipation or electrical connection. That pad's purpose follows the product design.
Example
Do not always connect the central pad to ground simply because the package is QFN. Check actual terminal functions and mounting instructions.
Key distinction
Package format describes structure, but does not determine every terminal's function.
