PIN DESCRIPTION
2. PIN DESCRIPTION
2.1 INTRODUCTION
The STPC Consumer integrates most of the func-
tionalities of the PC architecture. As a result, many
of the traditional interconnections between the
host PC microprocessor and the peripheral devic-
es are totally internal to the STPC Consumer. This
offers improved performance due to the tight cou-
pling of the processor core and these peripherals.
As a result many of the external pin connections
are made directly to the on-chip peripheral func-
tions.
Figure 2-1 shows the STPC Consumer’s external
interfaces. It defines the main busses and their
function. Table 2-1 describes the physical imple-
mentation listing signal types and their functional-
ities. Table 2-2 provides a full pin listing and de-
scription. Table 2-3 provides a full listing of the
STPC Consumer pin locations of package by
physical connection. Please refer to the pin alloca-
tion drawing for reference.
