Product Brief

Integrated EC000 Processor

The MC68306 is an integrated processor containing a 68EC000 processor and elements common to many

68000- and 68EC000-based systems. Designers of virtually any application requiring 68000-class

performance will find that the MC68306 reduces design time by providing valuable system elements pre-

packaged 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 shows a simplified block diagram of the MC68306.
