Overview
1.1.1 FlexCore Advantages
Developers face tough challenges in reducing product cost. By incorporating user-designed
logic and Motorola-supplied functions into a single FlexCore processor, a system designer
can realize significant savings in cost, power consumption, board space, and pin count. The
equivalent functionality can easily require 20 separate components. Each component might
have 16–64 pins, totaling over 350 connections. Each connection is a candidate for a bad
solder joint or misrouted trace. Each component is another part to qualify, purchase, inven-
tory, and maintain. Each component requires a share of the printed circuit board. Each com-
ponent draws power—often to drive large buffers and circuit board traces to get signals to
another chip. Each component must be individually placed and attached to a printed circuit
board. The signals between the core processor unit and a peripheral might not be compat-
ible nor run from the same clock, requiring time delays or other special design consider-
ations.
In a FlexCore integrated processor, the major functions and glue logic are all properly con-
nected internally, timed with the same clock, and fully tested. Only essential signals are
brought out to pins. The processor is assembled in a surface-mount package for the small-
est possible footprint.
1.1.2 FlexCore Module Types
The three types of FlexCore modules are:
The SCM68000 core processor is available as a hard module.
