AC Characteristics
(1) Clock Timing Ratings
(VCC
= 4.0 to 5.5 V, VSS = AVSS = 0 V)
*1 : The values assume a gear cycle of 1/16.
*2 : When the PLL is used, the lower-limit frequency of the input clock to the X0 and X1 pins determines depending
on the PLL multiplication.
At
× 1 multiplication : more than 8 MHz
At
× 2 to × 8 multiplication : more than 4 MHz

range, set the multiplier for
the internal clock not to let
the operating frequency
exceed 33 MHz.
