DVDD_M terminal of 10PIN connect to bypass condenser and don’t connect to power supply (3.3V) Please confirm the optimal oscillation circuit parameters applicable to your systems or products with the oscillator manufacturer in advance. VQFN040V6060 package exposes its frame of the backside of package. Note that this part is assumed to use after providing heat dissipation treatment to improve heat dissipation efficiency. Try to occupy as wide as possible with heat dissipation pattern not only on the board surface but also the backside.
