Maximum Current Values
See the “Operational Description” section for the maximum current values.
The maximum VTR current, I
from/to 0V to/from 3.3V. The total maximum current for the part is the unloaded value PLUS the maximum
current sourced by the pin that is driven by VTR. The pins that are powered by VTR are listed in the
“Trickle Power Functionality” section.
The maximum VCC current, I
from/to 0V to/from 3.3V.
Power Management Events (PME/SCI)
The LPC47N237 offers support for Power Management Events (PMEs), also referred to as System Control
Interrupt (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. See the “PME
Support” section.
