Absolute Maximum Ratings

Caution: Permanent damage to the LSI may result if absolute maximum ratings are exceeded.

Note 1. Connect the AVCC0, AVCC1, and VCC_USB pins to VCC, and the AVSS0, AVSS1, and VSS_USB pins to VSS.

When the A/D converter unit 0 is not to be used, connect the VREFH0 pin to VCC and the VREFL0 pin to VSS, respectively.

Do not leave these pins open. Insert capacitors of high frequency characteristics between the AVCC0 and AVSS0 pins, or

AVCC1 and AVSS1 pins. Place capacitors of about 0.1 µF as close as possible to every power supply pin and use the shortest

and heaviest possible traces.

Note 2. The listed values apply when pins P30, P31, and P32 are set for the TAMPIn or RTCICn (n = 0 to 2) functions, and pin PJ3 is set

for the EXCIN function.
