Product Brief
Dragon I^™—
High Performance Integrated Processor
The MC68349 Dragon I is the highest performance member of the Motorola M68300 family of integrated
processors. The MC68349 is designed to serve as the central processor of personal intelligent
communicators (PICs) and similar products requiring an optimal balance of performance, integration, cost,
and power consumption. The MC68349 is the first in a series of M68300 family integrated processors
designed specifically to support rigorous requirements of consumer-oriented intelligent personal electronics.
The MC68349 is based on the powerful CPU030 processor which combines a full 32-bit central processor
with a configurable instruction cache and dedicated data memory structures. The MC68349 also
incorporates a high-speed 32-bit dual direct memory access (DMA) controller, a two-channel serial
communications interface, and clock synthesis, power management functions, system protection features,
and a glueless memory interface.
The MC68349 is fully compatible with previous members of the M68000 family and offers a long-term future
migration path to successors based on MC68040 and MC68060 processors. The modular nature of the
MC68349 also provides for cost-effective migration paths to higher levels of integration in future products.
