Trickle Power Functionality

When the FDC37M81x is running under VTR

only, the PME wakeup events are active and (if

enabled) able to assert and nIO_PME pin active

low. The following lists the wakeup events.

• UART1 Ring Indicator

• UART2 Ring Indicator

• Keyboard data

• Mouse data

Maximum Current Values

Refer to the “Operational Description” section for

the maximum current values.

The maximum VTR current, ITR, is given with all

outputs open. The total maximum current

for the part is the unloaded value PLUS the

maximum current sourced by all pins that are

driven by VTR.

The maximum VCC current, ICC, is given with all

outputs open (not loaded).

Power Management Events (PME/SCI)

The FDC37M81x offers support for Power

Management Events (PMEs), also referred to as

System Control Interrupts (SCI) events. The

terms PME and SCI are used synonymously

throughout this document to refer to the

indication of an event to the chipset via the

assertion of the nIO_PME output signal on pin 4.

See the “PME Support” section.
