Notes:

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
