Notes:
1. Typical values at 25
°C.
2. “Max” means the highest value where the pin is guaranteed to be read as low.
3. These parameters are not tested in production.
4. “Min” means the lowest value where the pin is guaranteed to be read as high.
5. Although each I/O port can sink more than the test conditions (10 mA at V
CC = 5V, 5 mA at VCC = 3V, 2 mA at VCC = 1.8V)
under steady state conditions (non-transient), the following must be observed:
The sum of all I
OL, for ports A0, A3, B0 – B7, C7, D5 – D7 should not exceed 100 mA.
The sum of all I
OL, for ports A1 – A2, C0 – C6, D0 – D4 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.
6. The RESET pin must tolerate high voltages when entering and operating in programming modes and, as a consequence,
7. High Sink I/O pins are PD0, PD1, PD2 and PD3.
8. Although each I/O port can source more than the test conditions (10 mA at VCC = 5V, 5mA at VCC = 3V, 2 mA at VCC = 1.8V)
under steady state conditions (non-transient), the following must be observed:
The sum of all I
OH, for ports A2 – A3, B0 – B7, C6, D0 – D7 should not exceed 100 mA.
The sum of all IOH, for ports A0 – A1, C0 – C5, C7 should not exceed 100 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.
9. These are test limits, which account for leakage currents of the test environment. Actual device leakage currents are lower.
