New iDEN Integrated Digital Handset Powered by M.CORE Microcontroller.

AUSTIN, Texas--(BUSINESS WIRE)--Sept. 8, 1998--

Motorola's Newest DigitalDNA Technology Provides Extended Battery Life for Combination Digital Cellular Phone, Two-Way Radio and Pager

Motorola Inc.'s first M.CORE architecture-based product, the newly introduced iDEN i1000 integrated digital handset, is tailored to meet the needs of business professionals who require access to multiple communication services in a single device.

Demonstrating extremely rapid market success, as evidenced by the growing number of design wins, Motorola's M.CORE architecture was selected as the processor of choice for the i1000 phone because of its low power consumption, small size and cost-effectiveness.

The i1000 handset's small size (4.5 x 2.2 x 1.2 inches) and light weight (as little as 5 ounces) make it the first wearable integrated digital handset in the world. The M.CORE architecture's low-power operation helps the i1000 provide up to 180 minutes of talk time or up to 60 hours of standby time in multiservice mode or up to 75 hours in "phone-only" mode with a standard Lithium Ion battery.

"The M.CORE controller provided the iDEN designers with the technology to extend battery life for increased talk and standby time for this newest-generation product. The strong development-tools support for the M.CORE architecture was crucial in speeding product development and helping meet our product-introduction goals," said Jaime Borras, vice president of Motorola and director of technology, iDEN Subscriber Division.

Housed within the i1000 handset is the DSP56652 dual-core processor, which integrates the small but powerful M.CORE 32-bit core and a 16-bit DSP56600 on a single chip. By combining two cores on one low-voltage chip, the DSP56652 allows designers to minimize system- design complexity while reducing time to market.

"The DSP56652 delivers the performance required by users of the i1000 handset without draining the power-consumption budget, plus its very judicious use of code is cost-effective and saves memory," said Joyce Putscher, senior analyst, Cahners In-Stat.

Operating at 1.8 V, the DSP56652 is a cellular baseband processor that features substantial on-chip memory, a sophisticated interface that allows its two cores to function together seamlessly, and a strong peripheral set for cellular applications.

"We believe the M.CORE architecture will be the foundation and enabling technology for a wide range of telecommunications markets and applications. The DSP56652 represents what Motorola's DigitalDNA strategy is all about -- providing system solutions for innovative new products that make life better," remarked Jim Thomas, vice president and director of the M.CORE Technology Center.

The DSP56600 core is a 60 MIPS processing engine that executes one instruction every clock cycle. In cellular applications, the DSP converts the caller's voice to and from an appropriate digital representation and controls reliable transmission and reception of that digital signal via radio waves.

The DSP56600 core also includes a highly parallel instruction set with unique DSP addressing modes and position-independent code support. The M.CORE microcontroller utilizes a small memory footprint and unique power-saving features, all on a tiny, high-performance core.

The M.CORE architecture is a 32-bit Load/Store microRISC architecture with a fixed 16-bit instruction length, which allows for tremendous memory savings. While the M.CORE architecture is capable of up to 40 MIPS, the clock for the MCU side on the DSP56652 has been lowered to provide additional power savings and to leave room for future product performance.

Optimized at 1.8V and leading the industry in MIPS-per-watt, the M.CORE controller represents the leading edge in low-power microRISC technology.
