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, MCORETM and the Roaming FLEXTM 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 MCORE family of 32-bit microcontroller units (MCUs). The MCORE 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 MCORE 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 MCORE 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. A table of contents for this document appears on the following page.
