MMC2080/2075 Integrated Processor with
Roaming FLEX™ Decoder
Part 1 Introduction
The MMC2080/2075 is designed to provide the messaging and paging marketplace with a powerful and
flexible solution to carry communications design into the next millennium. The MMC2080 integrates two
of Motorola’s most successful product families, M•CORE™ and the Roaming FLEX™ alphanumeric
decoders, a combination that will set a new standard in the communications industry. Except for the FLEX
decoder, the MMC2075 offers all features of the MMC2080.
Both the The MMC2080/2075 are members of the low-power, high-performance M•CORE family of 32-bit
microcontroller units (MCUs). The M•CORE is a streamlined execution engine that provides many of the
performance enhancements found in mainstream reduced instruction set computers (RISCs). Combining
performance, speed, and cost efficiency in a compact, low-power design, the M•CORE microRISC
architecture is a natural solution for applications where battery life and systems cost are critical design goals.
Given that a total system’s components and processor core determine its power consumption, the instruction
set architecture (ISA) for the M•CORE is designed to optimize the trade-off between performance and total
power consumption. The result is system-wide reduction of total energy consumption with maintenance of
acceptable performance levels. Memory power consumption (both on-chip and external) is a major factor in
system energy consumption. By adopting 16-bit instruction encoding, and thus significantly decreasing the
memory bandwidth needed for a high rate of instruction execution, the MMC2080/2075 minimizes the
overhead of memory system energy consumption.
The MMC2080/2075 also reduces power consumption by coupling a fully static design with dynamic power
management and low-voltage operation. Versatile power management is achieved through automatic power
downs of any internal functional blocks not needed on a clock-by-clock basis. Power conservation modes
are also provided for absolute power conservation.
