| MOTOROLA SEMICONDUCTOR PRODUCT INFORMATION Product Brief Freescale Semiconductor, Inc. Order this document by DSP56002P/D DSP56002 DSP56L002 24-bit Digital Signal Processor The DSP56002 and the DSP56L002 are MPU-style general purpose Digital Signal Processors (DSPs), composed of an efficient 24-bit digital signal processor core, program and data memories, various peripherals, and support circuitry. The 56000-Family-compatible DSP core is fed by onchip program RAM, two independent data RAMs, and two data ROMs with sine and A-law and -law tables. The DSP56002/L002 contains a Serial Communication Interface (SCI), Synchronous Serial Interface (SSI), parallel Host Interface (HI), Timer/Event Counter, Phase-Locked Loop (PLL), and On-chip Emulation (OnCETM) port. This combination of features, illustrated in Figure 1, makes the DSP56002/L002 a cost-effective, high-performance solution for high-precision generalpurpose digital signal processing.
