ATmega48P/88P/168P/328P
Notes: 1. “Max” means the highest value where the pin is guaranteed to be read as low
2. “Min” means the lowest value where the pin is guaranteed to be read as high
3. Although each I/O port can sink more than the test conditions (20 mA at V
CC
= 5V, 10 mA at V
CC
= 3V) under steady state
conditions (non-transient), the following must be observed:
ATmega48P/88P/168P/328P:
1] The sum of all I
OL
, for ports C0 - C5, ADC7, ADC6 should not exceed 100 mA.
2] The sum of all I
OL
, for ports B0 - B5, D5 - D7, XTAL1, XTAL2 should not exceed 100 mA.
3] The sum of all I
OL
, for ports D0 - D4, RESET should not exceed 100 mA.
If I
OL
exceeds the test condition, V
OL
may exceed the related specification. Pins are not guaranteed to sink current greater
than the listed test condition.
4. Although each I/O port can source more than the test conditions (20 mA at V
CC
= 5V, 10 mA at V
CC
= 3V) under steady state
conditions (non-transient), the following must be observed:
ATmega48P/88P/168P/328P:
1] The sum of all I
OH
, for ports C0 - C5, D0- D4, ADC7, RESET should not exceed 150 mA.
2] The sum of all I
OH
, for ports B0 - B5, D5 - D7, ADC6, XTAL1, XTAL2 should not exceed 150 mA.
If II
OH
exceeds the test condition, V
OH
may exceed the related specification. Pins are not guaranteed to source current
greater than the listed test condition.
26.2.1 ATmega48P DC Characteristics
Notes: 1. Values with “Minimizing Power Consumption” enabled (0xFF).
2. Typical values at 25°C. Maximum values are test limits in production.
3. The current consumption values include input leakage current.
