Note 1: ICCis 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. 40k
).
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: VCCfalling at 8.5mv/
