Unit Notes VIH Input high voltage (digital pins) • 2.7 V ≤ VDD ≤ 3.6 V • 1.7 V ≤ VDD ≤ 2.7 V 0.7 × VDD 0.75 × VDD — — V V VIL Input low voltage (digital pins) • 2.7 V ≤ VDD ≤ 3.6 V • 1.7 V ≤ VDD ≤ 2.7 V — — 0.35 × VDD 0.3 × VDD V V VHYS Input hysteresis (digital pins) 0.06 × VDD — V IICDIO Digital pin negative DC injection current — single pin • VIN < VSS-0.3V -5 — mA 1 IICAIO Analog2, EXTAL0/XTAL0, and EXTAL1/XTAL1 pin DC injection current — single pin • VIN < VSS-0.3V (Negative current injection) • VIN > VDD+0.3V (Positive current injection) -5 — — +5 mA 3 IICcont Contiguous pin DC injection current —regional limit, includes sum of negative injection currents or sum of positive injection currents of 16 contiguous pins • Negative current injection • Positive current injection -25 — — +25 mA VRAM VDD voltage required to retain RAM 1.2 — V VRFVBAT VBAT voltage required to retain the VBAT register file VPOR_VBAT — V 1. All 5 V tolerant digital I/O pins are internally clamped to VSS through a ESD protection diode. There is no diode connection to VDD. If VIN greater than VDIO_MIN (=VSS-0.3V) is observed, then there is no need to provide current limiting resistors at the pads. If this limit cannot be observed then a current limiting resistor is required. The negative DC injection current limiting resistor is calculated as R=(VDIO_MIN-VIN)/|IIC|. 2. Analog pins are defined as pins that do not have an associated general purpose I/O port function. 3. All analog pins are internally clamped to VSS and VDD through ESD protection diodes. If VIN is greater than VAIO_MIN (=VSS-0.3V) and VIN is less than VAIO_MAX(=VDD+0.3V) is observed, then there is no need to provide current limiting resistors at the pads. If these limits cannot be observed then a current limiting resistor is required. The negative DC injection current limiting resistor is calculated as R=(VAIO_MIN-VIN)/|IIC|. The positive injection current limiting resistor is calcualted as R=(VIN-VAIO_MAX)/|IIC|. Select the larger of these two calculated resistances. 5.2.2 LVD and POR operating requirements Table 2.
