DSP56005

The DSP56005 is an MPU-style general purpose Digital Signal Processor (DSP), 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 a large program RAM, two independent data RAMs, and two data ROMs with sine and arc-tangent tables. Like the DSP56002, the DSP56005 contains a Serial Communication Interface (SCI), Synchronous Serial Interface (SSI), parallel Host Interface (HI), a 24-bit timer/event counter, and On-Chip Emulation (OnCE ™) port. Features of the DSP56005 include the large on-chip program memory, five Pulse Width Modulators (PWM), a watchdog timer, and an address decode pin for external peripherals. This combination of features, illustrated in Figure 1, makes the DSP56005 a cost-effective, high-performance solution for many DSP and control applications, especially in high-performance motor control, optical disk drives and audio processing.
