Enhanced Super I/O Controller with LPC Interface
Datasheet
7.7 VREF Pin
The LPC47M112 has a reference voltage pin input on pin 44 of the part. This reference voltage can be connected to
either a 5V supply or a 3.3V supply. It is used for the game port. See the “GAME PORT LOGIC” section.
7.8 Maximum Current Values
See the “Operational Description” section for the maximum current values.
The maximum VTR current, I
3.3V). 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 pins that are powered by VTR are as follows: GP42 / nIO_PME, IRTX2 / GP35,
GP53/TXD2 (IRTX), GP60 / LED1, GP61 / LED2. These pins, if configured as push-pull outputs, will source a
minimum of 6mA at 2.4V when driving.
The maximum VCC current, I
3.3V).
The maximum VREF current, I
3.3V).
7.9 Power Management Events (PME/SCI)
The LPC47M112 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 on pin 17. See the “PME Support” section.
