The following requirements must be met when powering up a device (refer to )LJXUH ):
• When ramping up the power supplies keep (VCCIO -VCC)MAX ≤ 500 mV. Deviation from this
recommendation can cause permanent damage to the device.
• VCCIO must lead VCC when ramping the device.
• The power supply must be greater than or equal to 400 µs to reach VCC. Ramping to
VCC/VCCIO before reaching 400 µs can cause the device to behave improperly.
