Internally-Generated Power Delivery
There are no specific power down sequencing and tracking requirements for the 82563EB/
82564EB silicon. The risk of latch-up or electrical overstress is small because only the charge
stored in the decoupling capacitors is left in the system.
The 82563EB/82564EB has two internal linear voltage regulator controllers. The controllers use
external transistors to generate 2 of the 3 required voltages: 1.9V (nominal) and 1.2V (nominal).
These two voltages are stepped-down from a 3.3V source.
