dspblok 21565 - Analog Devices ADSP-21565 SHARC DSP Module

The dspblok™ 21565 is a highly integrated DSP module that incorporates an Analog Devices’ ADSP-21565 SHARC DSP operating at 1 GHz, flash, EEProm, and a switching power supply to support the core voltage requirements. All the connections are brought out to standard 2mm dual row header footprints. The board is only 60mm x 60mm (2.36" x 2.36").

The dspblok 21565 also includes a USB transceiver. You can use the USB to upload DSP code via Danville's dspBootloader™.

Development couldn't be easier. You can connect to an Analog Devices ICE and write your code using Analog Devices CrossCore Embedded Studio. If you are starting a new project or designing your own target, you may want to use the dspblok Development Board. This board is convenient as a starting place to connect other development boards (data converters and I/O). It includes a power supply and computer connections to get you started.
