Datasheet
17
Pentium III Processor for the PGA370 Socket up to 750 MHz
2.5
Processor System Bus Clock and Processor Clocking
The BCLK input directly controls the operating speed of the system bus interface. All AGTL+
system bus timing parameters are specified with respect to the rising edge of the BCLK input. See
the P6 Family of Processors Hardware Developer's Manual for further details.
2.6
Voltage Identification
There are four voltage identification pins on the PGA370 socket. These pins can be used to support
automatic selection of VCCCORE voltages. These pins are not signals, but are either an open circuit
or a short circuit to VSS on the processor. The combination of opens and shorts defines the voltage
required by the processor core. The VID pins are needed to cleanly support voltage specification
variations on current and future processors. VID[3:0] are defined in Table 2. A ‘1’ in this table
refers to an open pin and a ‘0’ refers to a short to ground. The voltage regulator or VRM must
supply the voltage that is requested or disable itself.
To ensure a system is ready for current and future processors, the range of values in bold in Table 2
should be supported. A smaller range will risk the ability of the system to migrate to a higher
performance processor and/or maintain compatibility with current processors.
NOTES:
1. 0 = Processor pin connected to VSS.
2. 1 = Open on processor; may be pulled up to TTL VIH on baseboard.
3. To ensure a system is ready for the Intel Pentium III and Intel CeleronTM processors, the values in BOLD
in Table 2 should be supported.
Note that the ‘1111’ (all opens) ID can be used to detect the absence of a processor core in a given
socket as long as the power supply used does not affect these lines. Detection logic and pull-ups
should not affect VID inputs at the power source (see Section 7.0).
