MC68360 USER’S MANUAL
SECTION 1
INTRODUCTION
The MC68360 QUad Integrated Communication Controller (QUICC
) is a versatile one-
chip integrated microprocessor and peripheral combination that can be used in a variety of
controller applications. It particularly excels in communications activities. The QUICC (pro-
nounced “quick”) can be described as a next-generation MC68302 with higher performance
in all areas of device operation, increased flexibility, major extensions in capability, and
higher integration. The term "quad" comes from the fact that there are four serial communi-
cations controllers (SCCs) on the device; however, there are actually seven serial channels:
four SCCs, two serial management controllers (SMCs), and one serial peripheral interface
(SPI).
The purpose of this document is to describe the operation of all QUICC functionality.
Although this document has an overview of the CPU32+, the M68000PM/AD
M68000 Fam-
ily Programmer's Reference Manual should be used in addition to this document. The
CPU32RM/AD,
M68300 Family CPU32 Reference Manual, also provides information on the
CPU32.
