Note:
- All measurements done at 3.3V at 25℃
- VIL source < (GND – 0.3). Characterized but not tested.
- Any number and/or combination of I/O pins not excluded under IICL or IICH conditions are permitted provided the absolute instantaneous sum of the input injection currents from all pins do not exceed the specified ∑IICT limit. To limit the injection current, the user must insert a resistor in series RSERIES (in other words, RS), between the input source voltage and device pin. The resistor value is calculated according to:
- For negative Input voltages less than (GND – 0.3): RS ≥ absolute value of | ((VIL source – (GND – 0.3)) / IICL)
- For positive input voltages greater than (VDDIO + 0.3): RS ≥ ((VIH source – (VDDIO +0.3))/ IICH)
- For Vpin voltages greater than VDDIO + 0.3 and less than GND – 0.3: RS = the larger of the values calculated above
- High load = 50 pF and Standard load = 30 pF
- The drive strength of pads are as follows:
- 8x pads - PA0, PA1, PA3, PA4, PA5, PA6, PA7, PA8, PA9, PA10, PA13, PA14, PB10, PB11, PB12, PB13
- 4x pads - PA2, PB0, PB1, PB2, PB3, PB4, PB5, PB6, PB7, PB8, PB9
