The DSP56309 is intended
for applications benefiting
from a large amount of
internal memory, such as
wireless infrastructure
applications.
What’s New?
Rev. 7 includes the following
changes:
• Adds lead-free packaging and
part numbers.
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.
