Technical Data

DSP56301

24-Bit Digital Signal Processor

The DSP56301 is a member of the DSP56300 core family of programmable CMOS Digital Signal Processors

(DSPs). This family uses a high-performance, single clock cycle per instruction engine. Significant architectural

features of the DSP56300 core family include a barrel shifter, 24-bit addressing, instruction cache, and DMA. The

DSP56301 offers 80/100 MIPS using an internal 80/100 MHz clock at 3.0–3.6 volts. The DSP56300 core family

offers a rich instruction set and low power dissipation, as well as increasing levels of speed and power, enabling

wireless, telecommunications, and multimedia products.
