MOTOROLA Freescale Semiconductor, Inc. SEMICONDUCTOR TECHNICAL DATA Order this document by: DSP56651/D Rev 0, 6/98 Advance Information DSP56651 INTEGRATED CELLULAR BASEBAND PROCESSOR DEVELOPMENT IC Motorola designed the RAM-based DSP56651 emulation device to support the rigorous demands of developing applications for the cellular subscriber market. The high level of on-chip integration in the DSP56651 and its volume production companion device DSP56652 minimizes application system design complexity and component count, resulting in very compact implementations. This integration also yields very low-power consumption and cost-effective system performance. The DSP56651 chip combines the power of Motorola’s 32-bit MCORE TM MicroRISC Engine (MCU) and the DSP56600 digital signal processor (DSP) core with on-chip memory, protocol timer, and custom peripherals to provide a single-chip cellular base-band processor. Figure 1 shows the basic block diagram of the DSP56651. Freescale Semiconductor, Inc...
