What’s New?

Rev. 6 updates the

example clock input

circuits in Figure 2-1.

The DSP56309 is a member of the DSP56300

core family of programmable CMOS digital

signal processors (DSPs). The DSP56300 core

includes a barrel shifter, 24-bit addressing, an

instruction cache, and direct memory access

(DMA). The DSP56309 offers 100 MIPS 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.
