Two-layer board is specified as a 76 mm X 114 mm, 1.6 mm thick FR-4 material with 1-oz copper covering 20 % of the top & bottom layers. 2. Four-layer board is specified as a 76 mm X 114 mm, 1.6 mm thick FR-4 material with 1-oz copper covering 20 % of the top & bottom layers and 0.5-oz copper covering 90 % of the internal power plane and ground plane layers. 3. To calculate the die temperature for a given power dissipation 4. Τ j = Ambient Temperature + [ (Power Dissipation in Watts) * θ ja ] 5. To calculate the case temperature for a given power dissipation 6. Τ c = Τ j - [ (Power Dissipation in Watts) * ψ jt ] 5.7 Switching Characteristics— RESET Parameter Min Typ Max Unit Power supply current: Core and I/O operating: VDD1 PLL operating: VDDA With external memory and most ports operating: VDDIO 1.
