Note 1: ICC is measured with PBRST and all outputs open and inputs within 0.5V of supply rails.

Note 2: Measured with VCC ≥ 2.7V.

Note 3: Measured with VCC < 2.7V.

Note 4: PBRST has an internal pull-up resistor to VCC (typ. 40kΩ).

Note 5: Guaranteed by design at TA = 25°C.

Note 6: PBRST must be held low for a minimum of 20ms to guarantee a reset.

Note 7: VCC falling at 8.5mv/µs.
