Product Brief

December 2006

Revision 1.4

87427 ServerI/O with SensorPath^TMHealth Monitoring

The 87427 also incorporates a Floppy Disk Controller

(FDC), two serial ports (UARTs), a Keyboard and Mouse

Controller (KBC), General-Purpose Input/Output (GPIO),

GPIO extension for additional off-chip GPIO ports, and an

interrupt serializer for parallel IRQs.

General Description

The Winbond 87427 is targeted for a wide range of servers

workstations and high-end desktops that use the Low Pin

Count (LPC) bus for the host interface and an SMBus^®

interface for either a Baseboard Management Controller

(BMC) or mini-BMC (mBMC), both of which are optional.

Outstanding Features

For LPC and SMBus access, the 87427 features a fast

X-Bus, over which boot flash and I/O devices can be ac-

cessed. The 87427 supports X-Bus address line forcing

(to 0 or 1) to create memory windows for BIOS data storage.

■ Legacy-reduced Advanced I/O, optimized for high-end

platforms. Legacy modules: FDC, two Serial Ports

(UARTs) and a Keyboard and Mouse Controller (KBC).

■ SensorPath system health support for LMxx sensors,

fan monitor/control, and chassis intrusion detection, for

all platforms (i.e., with or without a BMC or mBMC).

When V_SBexists, the BMC or mBMC can access the

87427 and its fast X-Bus via SMBus. The SMBus also

controls serial port float, RTC access, and serial port inter-

connection (snoop and take-over modes). In addition, the

87427 provides routing of up to two selected LPC I/O

port transactions to the GPIO Extension Port.

■ 8/16-bit fast X-Bus extension for boot flash, memory

and I/O.

■ I/O-mapped and memory-mapped registers.

■ V_SB-powered SMBus access to modules and fast X-Bus.

The 87427 provides a V_SB-powered high-frequency clock

for on-chip peripherals; it also provides a configurable high-

frequency clock for other V_SB-powered platform components.

■ Two sets of BIOS code and data support, for main and

back-up BIOS.

■ Extremely low current consumption in Battery Backup

The 87427 supports SensorPath health monitor inter-

face to LMxx sensors, fan monitoring and control, and a

chassis intrusion detector.

mode.

■ Serial Interface for manageability (Serial Interface M).

Two-to-one multiplexing of Serial Ports 1 and 2.

The System Wake-Up Control (SWC) module supports flex-

ible wake-up and power-off request mechanisms for all plat-

forms (i.e., with or without BMC/mBMC).

■ 52 GPIO ports with a variety of wake-up events, plus

GPIO extension for additional off-chip GPIO ports.

■ Watchdog for autonomous system recovery for BIOS

The 87427 supports both I/O and memory mapping of

module registers and enables building legacy-free systems.

Boot process and for operating system use.

■ 128-pin TFBGA package (for blade applications) and

128-pin PQFP package.
