Notes:

1.

Does not apply to CLK/X1 pin, when configured as crystal oscillator input (X1).

2.

– 0.4V

6.

VDD = 5.5V, VIL = 0.7V (max), VIH = VDD

– 0.7V (min), Typ. Val = 1.12 mA/MHz (Not Tested), Ext.

1X CLK, IOL = IOH = 0

7.

Freq. = 1 MHz

8.

Does not apply to OUT2/X2 pin, when configured as crystal oscillator output (X2).

9.

Freq. = 1 MHz, but input clock not running. Static IDD current is exclusive of input/output drive

requirements and is measured with the clocks stopped and all inputs tied to VDD or VSS, configured

to draw minimum current.

10. Applies only during hardware reset for clock configuration options. Strapping current for logic HIGH.

11. Applies only during hardware reset for clock configuration options. Strapping current for logic LOW.

12. Inputs (RTSn, DTRn, TB) with Pullups tested @ Vin = 0.0V, VDD = 5.5V
