System Management Feature 
Specifications

The Dual-Core Intel Itanium processor 9000 and 9100 series includes a system 
management bus (SMBus) interface. This chapter describes the features of the SMBus 
and SMBus components.

6.1

System Management Bus

6.1.1

System Management Bus Interface

The processor includes an Itanium processor family SMBus interface which allows 
access to several processor features. The system management components on the 
processor include two memory components (EEPROMs) and a thermal sensing device 
(digital thermometer). The processor information EEPROM (PIROM) is programmed by 
Intel with manufacturing and feature information specific to the Dual-Core Intel 
Itanium processor 9000 and 9100 series. This information is permanently write-
protected. 

Section 6.2

 provides details on the PIROM. The other EEPROM is a scratch 

EEPROM that is available for other data at the system vendor’s discretion. The thermal 
sensor can be used in conjunction with the information in the PIROM and/or the Scratch 
EEPROM for system thermal monitoring and management. The thermal sensing device 
on the processor provides an accurate means of acquiring an indicator of the junction 
temperature of the processor core die. The thermal sensing device is connected to the 
anode and cathode of the processor on-die thermal diode. SMBus implementation on 
the processor uses the clock and data signals as defined by SMBus specifications.

6.1.2

System Management Interface Signals

Table 6-1

 lists the system management interface signals and their descriptions. These 

signals are used by the system to access the system management components via the 
SMBus.

Figure 6-1

 shows the logical schematics of SMBus circuitry on the processor and shows 

how the various system management components are connected to the SMBus. The 
reference to the System Board at the lower left corner of 

Figure 6-1

 shows how SMBus 

address configuration for multiple processors can be realized with resistor stuffing 
options.
