Specifications
Note: The embedded modules use a supervisory circuit with a 2.93V reset threshold. When
VCC falls to the threshold voltage, a reset pulse is issued, holding the output in active state.
When power rises above 2.93V, the reset remains for approximately 200 ms to allow the
system clock and other circuits to stabilize.
Warning: The rise time of the 3.3v power supply must be between 700 mS and 140ms and
the inrush current must be limited to less than 2 A. A rise time outside of these limits may
cause the device to malfunction and give a 3-1-3 diagnostic error.
