MC68HC16Z1TUT/D
more sensitive to power supply noise than the port drivers. When designing a multilayer board, simply
route the power and ground pins directly to the power and ground planes; when designing a two-layer
board, however, it is best to isolate the power bus that serves the core of the chip from the power bus
that serves the port drivers.
Figure 10 shows groups of pins that are powered by the same supply pins. Although only the 132-pin
plastic surface mount package is shown, the groups for the 144-pin package are the same. In each
group, the VDDE and VSSE pins that power a particular group are shown in bold face type. The VDDI and
VSSI pins are labeled as such. EXTAL and XTAL are powered only by VDDSYN.
When control of noise on the power buses is important, it is possible to isolate sections of the chip that
are particularly noisy. The data and address buses are particularly noisy because they continually
change state, and the same can be true of serial ports and timer pins. The amount of noise generated
by a particular pin is dependent upon the load being driven and the switching frequency. A designer
who knows which power and ground connections serve particular pins can shield other signal conduc-
tors from these noisy lines.
