SECTION 1
INTRODUCTION
The MC68306 is an integrated processor containing an MC68EC000 processor and
elements common to many MC68000- and MC68EC000-based systems. Designers of
virtually any application requiring MC68000-class performance will find that the MC68306
reduces design time by providing valuable system elements integrated in one chip. The
combination of peripherals offered in the MC68306 can be found in a diverse range of
microprocessor-based systems, including embedded control and general computing.
Systems requiring serial communication and dynamic random access memory (DRAM)
can especially benefit from using the MC68306.
The MC68306's high level of functional integration results in significant reductions in
component count, power consumption, board space, and cost while yielding much higher
system reliability and shorter design time. Complete code compatibility with the MC68000
affords the designer access to a broad base of established real-time kernels, operating
systems, languages, applications, and development tools, many of which are oriented
towards embedded control. Figure 1-1 shows a simplified block diagram of the MC68306.
