† Input current IPP will be a maximum of 50 mA only when programming EPROM.

NOTES:

6. Single chip mode, ports configured as inputs or outputs with no load. All inputs

≤ 0.2 V or ≥ VCC – 0.2V.

7. XTAL2/CLKIN is driven with an external square-wave signal with 50% duty cycle and rise and fall times less than 10 ns. Current

can be higher with a crystal oscillator. At 5-MHz SYSCLK, this extra current = 0.01 mA x (total load capacitance + crystal capacitance

in pF).
