ATtiny28L/V

1062E–10/01

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

= 5V, 10 mA at V

= 3V) under steady-state

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

1] The sum of all I

, for all ports, should not exceed 300 mA.

2] The sum of all I

, for port D0 - D7 and XTAL2 should not exceed 100 mA.

If I

exceeds the test condition, V

may exceed the related specification.

Pins are not guaranteed to sink current greater than the listed test conditions.

4. Although each I/O port can source more than the test conditions (3 mA at V

= 5V, 1.5 mA at V

= 3V) under steady-state

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

1] The sum of all I

, for all ports, should not exceed 300 mA.

2] The sum of all I

, for port D0 - D7 and XTAL2 should not exceed 100 mA.

If I

exceeds the test condition, V

may exceed the related specification.

Pins are not guaranteed to source current greater than the listed test conditions.

5. Minimum V

for power-down is 1.5V.
