Electrical Specifications
3.1
Power and Ground Pins
For clean, on-chip power distribution, the processor will have a large number of V
CC
(power) and VSS (ground) inputs. All power pins must be connected to VCC power
planes while all VSS pins must be connected to system ground planes. Use of multiple
power and ground planes is recommended to reduce I*R drop. Please contact your
Intel representative for more details. The processor VCC pins must be supplied the
voltage determined by the VID (Voltage ID) pins.
3.2
FSB Clock (BCLK[1:0]) and Processor Clocking
BCLK[1:0] directly controls the FSB interface speed as well as the core frequency of the
processor. As in previous generation processors, the Intel Core Duo processor and Intel
Core Solo processors’ core frequency is a multiple of the BCLK[1:0] frequency. The
processor uses a differential clocking implementation.
3.3
Voltage Identification
The processor uses seven voltage identification pins, VID[6:0], to support automatic
selection of power supply voltages. The VID pins for the processor are CMOS outputs
driven by the processor VID circuitry. Table 2 specifies the voltage level corresponding
to the state of VID[6:0]. A 1 in this refers to a high-voltage level and a 0 refers to low-
voltage level.
