ATmega48PA/88PA/168PA/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 VCC = 5V, 10 mA at VCC = 3V) under steady state

conditions (non-transient), the following must be observed:

ATmega48PA/88PA/168PA/328P:

1] The sum of all IOL, for ports C0 - C5, ADC7, ADC6 should not exceed 100 mA.

2] The sum of all IOL, 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 IOL exceeds the test condition, VOL 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 VCC = 3V) under steady state

conditions (non-transient), the following must be observed:

ATmega48PA/88PA/168PA/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 IOH, for ports B0 - B5, D5 - D7, ADC6, XTAL1, XTAL2 should not exceed 150 mA.

If II

OH exceeds the test condition, VOH may exceed the related specification. Pins are not guaranteed to source current

greater than the listed test condition.

ATmega48PA DC Characteristics

Notes:

1. Values with “Minimizing Power Consumption” enabled (0xFF).

2. Typical values at 25

°C. Maximum values are characterized values and not test limits in production.

3. The current consumption values include input leakage current.
