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:
1] The sum of all I
OL, for all ports, should not exceed 300 mA.
2] The sum of all IOL, for port D0 - D7 and XTAL2 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 conditions.
4. Although each I/O port can source more than the test conditions (3 mA at VCC = 5V, 1.5 mA at VCC = 3V) under steady-state
conditions (non-transient), the following must be observed:
1] The sum of all I
OH, for all ports, should not exceed 300 mA.
2] The sum of all IOH, for port D0 - D7 and XTAL2 should not exceed 100 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 conditions.
5. Minimum VCC for power-down is 1.5V.
6. When entering Power-down, PORTA2 bit in PORTA register should be set.
