1. Typical values at 25°C. Maximum values are characterised and not production test limits.
2. “Min” means the lowest value where the pin is guaranteed to be read as high.
3. “Max” means the highest value where the pin is guaranteed to be read as low.
4. Although each I/O port can sink more than the test conditions (10 mA at V
5. Although each I/O port can source more than the test conditions (10 mA at V
6. The RESET pin must tolerate high voltages when entering and operating in programming modes and, as a consequence,
7. All I/O modules are turned off (PRR = 0xFF) for all I
8. Brown-Out Detection (BOD) disabled.
conditions (non-transient), the following must be observed:
1] The sum of all IOL, for all ports, should not exceed 60 mA.
If IOL exceeds the test condition, VOL may exceed the related specification. Pins are not guaranteed to sink current greater
than the listed test condition.
conditions (non-transient), the following must be observed:
1] The sum of all IOH, for all ports, should not exceed 60 mA.
If IOH exceeds the test condition, VOH may exceed the related specification. Pins are not guaranteed to source current
greater than the listed test condition.
