Power and Grounding
The fundamental power and ground requirements of the
AMD-K6 processor remain unchanged with the integration of
0.25-micron process technology. For information about
decoupling recommendations and pin connection requirements
of the AMD-K6 processor Model 7, see the AMD-K6^® Processor
Power Supply Design Application Note, order# 21103 and Chapter
13, “Power and Grounding” on page 229.
Power Connections
The AMD-K6 processor is a dual voltage device. Two separate
supply voltages are required— V_CC2 and V_CC3. V_CC2 provides the
core voltage for the processor and V_CC3 provides the I/O voltage.
See “Electrical Data” on page 233 for the value and range of
V_CC2 and V_CC3.
There are 28 V_CC2, 32 V_CC3, and 68 V_SS pins on the AMD-K6
processor. (See “Pin Designations” on page 269 for all power
and ground pin designations.) The large number of power and
ground pins are provided to ensure that the processor and
package maintain a clean and stable power distribution
network.
For more information about power connections requirements
for the AMD-K6 processor Model 7, see Chapter 13, “Power and
Grounding” on page 229.
