General Description
The National Semiconductor
PC8741x family of LPC Serv-
erI/O devices (“
PC8741x
”) comprises highly integrated Ad-
vanced I/O products. The PC8741x is targeted for a wide
rangeofserversandworkstationsthatusetheLowPinCount
(LPC) bus for the host interface and the serial ACCESS.bus
or SMBus
for the embedded controller interface.
The PC8741x features an X-Bus extension for read and write
operations over the X-Bus for both LPC and ACCESS.bus
cycles. Boot Flash and I/O devices can be accessed over this
X-Bus.
Embedded controllers can access the PC8741x and its X-Bus
via the ACCESS.bus or SMBus serial interface when V
SB
exists, regardless of the LPC bus state. Some of the
PC8741x logical devices can be disabled, or their pins can be
floated, under control of the V
SB
-powered serial bus.
The PC8741x provides a V
SB
-powered high-frequency clock
for on-chip peripherals and for other V
SB
-powered platform
components.
The PC8741x’s extended wake-up support complements the
chipset’s ACPI controller and the platform embedded control-
lers. The PC8741x can monitor the Power and Sleep buttons
and control the power supply of simple platforms that lack an
embedded controller. The System Wake-Up Control (SWC)
module is powered by V
SB
and V
BAT
power supplies. It sup-
ports flexible wake-up and power-off request mechanisms in
any sleep state. It features Main and Standby power-on
elapsed-time counters.
The PC8741x also incorporates a Floppy Disk Controller
(FDC), two serial ports (UARTs), a Keyboard and Mouse
Controller (KBC), a Real-Time Clock (RTC), a fully compliant
IEEE 1284 Parallel Port, General-Purpose Input/Output
(GPIO) for a total of 51 ports and an Interrupt Serializer for
Parallel IRQs.
