ABSOLUTE MAXIMUM RATINGS
Stresses greater than those listed in Table 14 may cause perma-
nent damage to the device. These are stress ratings only.
Functional operation of the device at these or any other condi-
tions greater than those indicated in the operational sections of
this specification is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device
reliability.
Table 14 specifies the maximum total source/sink (IOH/IOL) cur-
rent for a group of pins and for individual pins. Permanent
damage can occur if this value is exceeded. To understand this
specification, if pins PF0 and PF1 from Group 1 in Table 16
were sourcing or sinking 10 mA each, the total current for those
pins would be 20 mA. This would allow up to 35 mA total that
could be sourced or sunk by the remaining pins in the group
without damaging the device. It should also be noted that the
maximum source or sink current for an individual pin cannot
exceed 25 mA. The list of all groups and their pins are shown in
Table 16. Note that the VOH and VOL specifications have separate
per-pin maximum current requirements, see the Electrical
ESD SENSITIVITY

Internal Supply Voltage (VDDINT)
– 0.3 V to +1.50 V
External (I/O) Supply Voltage (VDDEXT)–0.3 V to +3.8 V
Input Voltage1, 2
1 Applies to 100% transient duty cycle. For other duty cycles see Table 15.
2 Applies only when VDDEXT is within specifications. When VDDEXT is outside speci-
fications, the range is VDDEXT ± 0.2 Volts.
– 0.5 V to +3.6 V
Output Voltage Swing
– 0.5 V to VDDEXT+0.5 V
IOH/IOL Current per Pin Group
55 mA (Max)
IOH/IOL Current per Individual Pin
25 mA (Max)
Storage Temperature Range
– 65°C to +150°C
Junction Temperature While Biased
(Non-Automotive Models)
+110°C
Junction Temperature While Biased
(Automotive Models)
+115°C
Table 15. Maximum Duty Cycle for Input Transient Voltage1
1 Applies to all signal pins with the exception of CLKIN, XTAL, EXT_WAKE.

2 The individual values cannot be combined for analysis of a single instance of
overshoot or undershoot. The worst case observed value must fall within one of
the voltages specified, and the total duration of the overshoot or undershoot
(exceeding the 100% case) must be less than or equal to the corresponding duty
cycle.
VIN Max (V)
Maximum Duty Cycle
3
3 Duty cycle refers to the percentage of time the signal exceeds the value for the
100% case. The is equivalent to the measured duration of a single instance of
overshoot or undershoot as a percentage of the period of occurrence.

ESD (electrostatic discharge) sensitive device.
Charged devices and circuit boards can discharge
without detection. Although this product features
patented or proprietary circuitry, damage may occur
on devices subjected to high energy ESD. Therefore,
proper ESD precautions should be taken to avoid
performance degradation or loss of functionality.
