Notes: 1. “Typ.", typical values at 25°C. Maximum values are characterized values and not test limits in production.
2. "Max.” means the highest value where the pin is guaranteed to be read as low.
3. “Min.” means the lowest value where the pin is guaranteed to be read as high.
4. Although each I/O port can sink more than the test conditions (10 mA at Vcc= 5V, 5 mA at Vcc = 3V) under steady state con-
ditions (non-transient), the following must be observed:
- The sum of all IOL, for all ports, should not exceed 120 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.
5. Although each I/O port can source more than the test conditions (10 mA at Vcc = 5V, 5 mA at Vcc = 3V) under steady state
conditions (non-transient), the following must be observed:
- The sum of all IOH, for all ports, should not exceed 120 mA.
If IOH exceeds the test condition, VOH may exceed the related specification. Pins are not guaranteed to source current
greater than the listed test condition.
6. Values using methods described in “Minimizing Power Consumption” on page 45. Power Reduction is enabled
(PRR = 0xFF) and there is no I/O drive.
7. BOD Disabled.
