1 / 108 page  Freescale Semiconductor Technical Data Advance Information DSP56309 Rev. 7, 2/2005 © Freescale Semiconductor, Inc., 1996, 2005. All rights reserved. DSP56309 24-Bit Digital Signal Processor The DSP56309 is a member of the DSP56300 core family of programmable CMOS DSPs. The DSP56300 core includes a barrel shifter, 24-bit addressing, an instruction cache, and direct memory access (DMA). The DSP56309 offers 100 MMACS at 3.0–3.6 V using an internal 100 MHz clock. The large internal memory is ideal for wireless infrastructure and wireless local-loop applications. The DSP56300 core family offers a new level of performance in speed and power provided by its rich instruction set and low-power dissipation, thus enabling a new generation of wireless, multimedia, and telecommunications products.
