PRELIMINARY INFORMATION

Electrical Data
9.1
Power and Grounding
Power Connections
The AMD-K5 processor includes 53 V
CC
and 53 V
SS
pins for
clean, on-chip power distribution at high frequencies. Power
and ground connections must be made to all external V
CC
and
GND pins, respectively. All V
CC
pins must be connected to the
circuit board V
CC
plane, and all V
SS
pins must be connected to
the circuit board GND plane. Table 14 on page 58 provides the
DC characteristics of the processor.
Connection
Recommendations
I
Emphasize decoupling capacitance near the AMD-K5
processor
Driving address and data buses into large capacitive loads
at high frequencies can cause transient power surges
Low inductance capacitors and circuit paths provide the
best performance at high frequencies
Inductance can be reduced by shortening circuit board
paths as much as possible
Capacitors specifically for PGA packaging are commer-
cially available
NC pins shall be unconnected
Always connect unused inputs to an appropriate signal
level
Unused active Low inputs should be connected to V
CC
through a pull-up resistor
Pull-up resistors of 20 k
should be used
Unused active High inputs should be connected to GND
