Hot-selling and scarce MC68306FC16A Microprocessor IC QFP spot stock

Product Descriptions

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.
