Parameter Min Typ Max1 Unit Comments Input Voltage, High (VIH) 2.0 IOVDD V Input Voltage, Low (VIL) 0.8 V Input Leakage, High (IIH) 1 μA Excluding MCLKI Input Leakage, Low (IIL) 1 μA Excluding MCLKI and bidirectional pins Bidirectional Pin Pull-Up Current, Low 150 μA MCLKI Input Leakage, High (IIH) 3 μA MCLKI Input Leakage, Low (IIL) 3 μA High Level Output Voltage (VOH), IOH = 2 mA 2.0 V Low Level Output Voltage (VOL), IOL = 2 mA 0.8 V Input Capacitance 5 pF GPIO Output Drive 2 mA 1 Maximum specifications are measured across a temperature range of −40°C to +130°C (case), a DVDD range of 1.62 V to 1.98 V, and an AVDD range of 2.97 V to 3.63 V. POWER Table 4. Parameter Min Typ Max1 Unit SUPPLY VOLTAGE Analog Voltage 3.3 V Digital Voltage 1.8 V PLL Voltage 3.3 V IOVDD Voltage 3.3 V SUPPLY CURRENT Analog Current (AVDD and PVDD) 50 85 mA Digital Current (DVDD) 40 60 mA Analog Current, Reset 35 55 mA Digital Current, Reset 1.5 4.5 mA DISSIPATION Operation (AVDD, DVDD, PVDD)2 286.5 mW Reset, All Supplies 118 mW POWER SUPPLY REJECTION RATIO (PSRR) 1 kHz, 200 mV p-p Signal at AVDD 50 dB 1 Maximum specifications are measured across a temperature range of −40°C to +130°C (case), a DVDD range of 1.62 V to 1.98 V, and an AVDD range of 2.97 V to 3.63 V. 2 Power dissipation does not include IOVDD power because the current drawn from this supply is dependent on the loads at the digital output pins.
