PRELIMINARY
11
The following sections describe recommended electri-
cal connections for the Am5
X
86 microprocessors and
electrical specifications.
Electrical Data
11.1 Power and Grounding
11.1.1 Power Connections
Am5
X
86 microprocessors with 16 Kbytes of cache have
modest power requirements. However, the high clock
frequency output buffers can cause power surges as
multiple output buffers drive new signal levels simulta-
neously. For clean, on-chip power distribution at high
frequency, 23 V
CC
pins
and 28 V
SS
pins feed the micro-
processor in the 168-pin PGA package. The 208-pin
SQFP package includes 53 V
CC
pins and 38 V
SS
pins.
Power and ground connections must be made to all
external V
CC
and V
SS
pins of the microprocessors. On a
circuit board, all V
CC
pins must connect to a V
CC
plane.
Likewise, all V
SS
pins must connect to a common GND
plane.
The Am5
X
86 microprocessor family requires only 3.3 V
as input power. Unlike other 3-V processors, the
Am5
X
86 microprocessor family does not require a
V
CC5
input of 5 V to indicate the presence of 5-V I/O
devices on the system motherboard. For socket com-
patibility, this pin is INC, allowing the Am5
X
86 CPU to
operate in 3-V sockets in systems that use 5-V I/O.
11.1.2 Power Decoupling Recommendations
Liberal decoupling capacitance should be placed near
the microprocessor. The microprocessor, driving its 32-
bit parallel address and data buses at high frequencies,
can cause transient power surges, particularly when
driving large capacitive loads.
Low inductance capacitors and interconnects are rec-
ommended for best high-frequency electrical perfor-
mance. Inductance can be reduced by shortening circuit
board traces between the microprocessor and the de-
coupling capacitors. Capacitors designed specifically
for use with PGA packages are commercially available.
11.1.3 Other Connection Recommendations
For reliable operation, always connect unused inputs to
an appropriate signal level. Active Low inputs should be
connected to V
CC
through a pull-up resistor. Pull-ups in
the range of 20 K
are recommended. Active High in-
puts should be connected to GND.
