9. Application Guidelines
9.1 Power Supply sequencing and Reset Timing
There are strict power sequencing and reset timing requirements.
Power up the I/O voltage (3.3V) first and hold NRESET_MOD low.
The core voltage (1.2V) must never be higher than (I/O voltage +0.5 V).
The core voltage (1.2V) must be within the specified core voltage limits less than 300ms after
the I/O voltage (3.3V) reaches the specified I/O voltage limits.
Throughout the power down process, the 3.3V supply must maintain a higher voltagethan the
1.2V supply, until both have reached ground potential.
To assure a proper IC reset, the power supplies must be present for a minimum time of 2ms
before NRESET_MOD is de-asserted.
Please see the power and reset timing figure in Section 9.1.1 below.
