PERSONAL INTELLIGENT COMMUNICATIONS
Representing a new class of consumer electronics, the PIC is oriented towards providing maximum personal
productivity to its user in a form-factor emphasizing low cost, minimal physical size, extended operation on
batteries, seamless communications in a complex wireless/wireline environment, and extreme ease-of-use.
The solution to the needs of the PIC applications requires a carefully selected balance of performance and
integration to satisfy the system's functional requirements while also meeting rigorous cost, weight, and
power consumption. The MC68349 was developed to the specifications of General Magic and its Alliance
Founders and, coupled with the proprietary Astro™ circuit, provides the complete digital core of a PIC.
The MC68349 represents a carefully selected balance of capabilities oriented towards enabling the PIC
vision:
• Advanced Motorola CMOS Process for Proven Reliability and Low Cost
• Static Design and Extensive Power Management for Long Battery Life
• Highly Integrated for Low Power, Low System Cost and High Reliability
• CPU030 Provides 8 to 10 Sustained MIPS for Support of Advanced User Interfaces
• Integration of Key System Functions for Performance/Power Optimizations
• M68000 Architecture Provides Strong Software Base and Upward Migration Paths
ADDITIONAL APPLICATION AREAS
While specifically optimized for the needs of personal intelligent communications, the MC68349 was
partitioned to provide the general-purpose elements of the PIC application while highly specialized features
were placed in a proprietary companion circuit. Thus, the MC68349 can provide substantial benefit to other
application areas as well.
In general, applications requiring moderate performance, low power consumption, high-bandwidth DMA, and
cost-effectiveness can be well-serviced by the MC68349. In addition, since the MC68349 is a member of the
M68000 family, its users have access to a broad range of superior support tools and services to facilitate
rapid system development and deployment.
Application areas suited to the MC68349 include:
• Personal Digital Assistants (PDAs)
• I/O Processors for High-Performance Systems
• Real-Time Control Processors
• Sophisticated 32-Bit DMA Controllers
