[1] Typical ratings are not guaranteed. The values listed are at room temperature (25
°
C), nominal supply voltages.
[2] Core and internal rail.
[3] External rail.
[4] If V
DD(IO)
< 3.0 V, the I/O pins are not 5 V tolerant and the ADC input voltage is limited to V
DD(ADC)
= 3.0 V.
[5] If V
DD(ADC)
< 3.0 V, the I/O pins are not 5 V tolerant.
[6] The RTC typically fails when V
DD(RTC)
drops below 1.6 V.
[7] Including voltage on outputs in 3-state mode.
[8] V
DD(IO)
supply voltages must be present.
[9] 3-state outputs go into 3-state mode when V
DD(IO)
is grounded.
[10] Accounts for 100 mV voltage drop in all supply lines.
[11] Allowed as long as the current limit does not exceed the maximum current allowed by the device.

DD(ADC)
= 3.3 V and V
DD(IO)
= 3.3 V for 10-bit resolution at full speed; V
DD(ADC)
= 2.6 V, V
DD(IO)
= 2.6 V for
8-bit resolution at full speed.
[2] The ADC is monotonic, there are no missing codes.
[3] The differential linearity error (E
D
) is the difference between the actual step width and the ideal step width. See
Fig 4.
[4] The integral non-linearity (E
L(adj)
) is the peak difference between the center of the steps of the actual and the ideal transfer curve after
appropriate adjustment of gain and offset errors. See
Fig 4.
[5] The offset error (E
O
) is the absolute difference between the straight line which fits the actual curve and the straight line which fits the
ideal curve. See
Fig 4.
[6] The gain error (E
G
) is the relative difference in percent between the straight line fitting the actual transfer curve after removing offset
error and the straight line which fits the ideal transfer curve. See
Fig 4.
[7] The absolute error (E
T
) is the maximum difference between the center of the steps of the actual transfer curve of the non-calibrated
ADC and the ideal transfer curve. See
Fig 4.
