Notes: 1. Regardless of whether or not the PLL is used, connect V

DD-PLL1/2

, V

DDA-PLL1

and V

DDQ-PLL1/2

to

the power supply, and V

SS-PLL1/2

, V

SSA-PLL1

and V

DDQ-PLL1/2

to GND. The LSI may be damage

when not filling this.

2. The current dissipation values are for V

IH

min = V

DDQ

−0.5 V and V

IL

max = 0.5 V with all

output pins unload.
