Product Brief

Integrated Processor With DMA

The MC68340 is a high-performance 32-bit integrated processor with direct memory access (DMA),

combining an enhanced M68000-compatible processor, 32-bit DMA, and other peripheral subsystems on a

single integrated circuit. The MC68340 CPU32 delivers 32-bit CISC processor performance from a lower

cost 16-bit memory system. The combination of peripherals offered in the MC68340 can be found in a

diverse range of microprocessor-based systems, including embedded control and general computing.

Systems requiring very high-speed block transfers of data can especially benefit from the MC68340's DMA.

The MC68340'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. The 3.3-V MC68340V is particularly attractive to applications requiring a very tight power budget.

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 oriented

towards embedded control. Figure 1 shows a block diagram of the MC68340.
