ATmega48A/PA/88A/PA/168A/PA/328/P [DATASHEET]

Atmel-8271H-AVR- ATmega-Datasheet_08/2014

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 (20mA at V

CC

 = 5V, 10mA at V

CC

 = 3V) under steady state conditions (non-transient), the 

following must be observed:
ATmega168P:
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

4.

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:
ATmega168P:
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

Notes:

1.

Results obtained using external clock and methods described in 

. Power reduction fully enabled (PRR = 0xFF) 

and with no I/O drive.

2.

Typical values at 25°C. Maximum values are test limits in production

3.

The current consumption values include input leakage current
