3.3 AC Electrical Characteristics
Timing waveforms in Section 3.3 are tested using the V
IL and VIH levels specified in the DC Characteristics
table. In Figure 3-2 the levels of V
IH and VIL for an input signal are shown.
8.
This low-voltage interrupt monitors the VDDA external power supply. VDDA is generally connected to the same potential
as VDD via separate traces. If VDDA drops below VEIO, an interrupt is generated. Functionality of the device is guaranteed
under transient conditions when VDDA>VEIO (between the minimum specified VDD and the point when the VEIO interrupt is
generated).
9.
This low voltage interrupt monitors the internally regulated core power supply. If the output from the internal voltage is
regulator drops below VEIC, an interrupt is generated. Since the core logic supply is internally regulated, this interrupt will not
be generated unless the external power supply drops below the minimum specified value (3.0V).
10. Power
on reset occurs whenever the internally regulated 2.5V digital supply drops below 1.5V typical. While power is
ramping up, this signal remains active as long as the internal 2.5V is below 1.5V typical, no matter how long the ramp-up rate
is. The internally regulated voltage is typically 100mV less than VDD during ramp-up, until 2.5V is reached, at which time it
self-regulates.
