Electrical Specifications (Continued)

Notes:

All power sources must be connected to the SC2200,

even if the function is not used

VSB,VSBL and VBAT must be on if any other voltage is

applied. VSB and VBAT voltages can be applied sepa-

rately. See Section 8.3.15 "Power-Up Sequencing" on

page 424.

The power planes of the SC2200 can be turned on or

off. For more information, see Section 5.2.9 "Power

Management Logic" on page 167.

It is recommended that the voltage difference between

VCCCRT,VCORE and VSBL be less than 0.25V, in order

to reduce leakage current. If the voltage difference

exceeds 0.25V, excessive leakage current is used in

gates that are connected on the boundary between

voltage domains.

It is recommended that the voltage difference between

VIO and VSB be less than 0.25V, in order to reduce

leakage current. If the voltage difference exceeds

0.25V, excessive leakage current is used in gates that

are connected on the boundary between voltage

domains.
