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 source more than the test conditions (20mA at V
CC
= 5V, 10mA at V
CC
= 3V) under steady
state conditions (non-transient), the following must be observed:
Atmel ATmega48PA/88PA/168PA:
1] The sum of all I
OH
, for ports C0 - C5, D0- D4, ADC7, RESET should not exceed 150mA.
2] The sum of all I
OH
, for ports B0 - B5, D5 - D7, ADC6, XTAL1, XTAL2 should not exceed 150mA.
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.
4. Although each I/O port can sink more than the test conditions (20mA at V
CC
= 5V, 10mA at V
CC
= 3V) under steady state
conditions (non-transient), the following must be observed:
Atmel ATmega48PA/88PA/168PA:
1] The sum of all I
OL
, for ports C0 - C5, ADC7, ADC6 should not exceed 100mA.
2] The sum of all I
OL
, for ports B0 - B5, D5 - D7, XTAL1, XTAL2 should not exceed 100mA.
3] The sum of all I
OL
, for ports D0 - D4, RESET should not exceed 100mA.
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.
