Datasheet
Features
The processor SMBus implementation uses the clock and data signals of the V1.1 System
Management Bus Specification. It does not implement the SMBSUS# signal. Layout and routing
guidelines are available in the appropriate platform design guidelines document and the SMBus
and I2C Bus Design Guide application note.
For platforms which do not implement any of the SMBus features found on the processor, all of the
SMBus connections,
except SM_VCC, to the socket pins may be left unconnected (SM_ALERT#,
SM_CLK, SM_DAT, SM_EP_A[2:0], SM_TS_A[1:0], SM_WP). SM_VCC provides power to the
VID generation logic in addition to supplying the SMBus and must be supplied with 3.3 volt power
to assure correct setting of the processor core voltage (V
CC).
NOTE: Actual implementation may vary. For use in general understanding of the architecture. All SMBus pull-up
and pull-down resistors are 10K
and located on the processor.
6.4.1
Processor Information ROM (PIROM)
The lower half (128 bytes) of the SMBus memory component is an electrically programmed read-
only memory with information about the processor. This information is permanently write-
protected. Table 35 shows the data fields and formats provided in the Processor Information ROM
(PIROM).
