Atmel ATmega16/32/64/M1/C1
Note: 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 (10mA at V
CC
= 5V, 6mA at V
CC
= 3V) under steady state con-
ditions (non-transient), the following must be observed:
1] The sum of all IOL, for ports B0 - B1, C2 - C3, D4, E1 - E2 should not exceed 70mA.
2] The sum of all IOL, for ports B6 - B7, C0 - C1, D0 -D3, E0 should not exceed 70mA.
3] The sum of all IOL, for ports B2 - B5, C4 - C7, D5 - D7 should not exceed 70mA.
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.
