Power and Grounding
The AMD-K6-IIIE+ processor is a dual voltage device. Two
separate supply voltages are required: V
See “Operating Ranges” on page 288 for the value and range of
V
The power and ground pins for each package are listed in
Table 76 on page 327 and Table 78 on page 331. Table 74 on
page 323 lists the pin differences between the two packages.
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 proper operation and functionality, all V
pins must be connected to the appropriate planes in the circuit
board. The power planes have been arranged in a pattern to
simplify routing and minimize crosstalk on the circuit board.
The isolation region between two voltage planes must be at
least 0.254mm if they are in the same layer of the circuit board.
( S ee Figure 1 03 o n p a ge 2 94 .) In ord er t o ma int ain a
low-impedance current sink and reference, the ground plane
must never be split.
Although the AMD-K6-IIIE+ processor has two separate supply
voltages, there are no special power sequencing requirements.
The best procedure is to minimize the time between which V
