Product Brief
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 on-
chip program RAM, two independent data RAMs, and two data ROMs with sine and A-law and
Serial Interface (SSI), parallel Host Interface (HI), Timer/Event Counter, Phase-Locked Loop
(PLL), and On-chip Emulation (OnCE™) port. This combination of features, illustrated in Figure 1,
makes the DSP56002/L002 a cost-effective, high-performance solution for high-precision general-
purpose digital signal processing.
