3 PIN DESCRIPTION
3.1. INTRODUCTION
The STPC Industrial integrates most of the func-
tionalities of the PC architecture. Therefore, many
of the traditional interconnections between the
host PC microprocessor and the peripheral devic-
es are totally internal to the STPC Industrial. This
offers improved performance due to the tight cou-
pling of the processor core and it’s peripherals. As
a result many of the external pin connections are
made directly to the on-chip peripheral functions.
Figure 3-1 shows the STPC Industrial’s external
interfaces. It defines the main busses and their
function. Table 3-1 describes the physical imple-
mentation listing signal types and their functionali-
ties. Table 3-2 provides a full pin listing and de-
scription.
Table 3-4 provides a full listing of the STPC Indus-
trial package pin location physical connection.
Please refer to the pin allocation drawing for refer-
ence.
Due to the number of pins available for the pack-
age, and the number of functional I/Os, some pins
have several functions, selectable by strap option
on Reset. Table 3-3 provides a summary of these
pins and their functions.
