The dspblok™ 21489-100 is a highly integrated DSP module that incorporates an Analog Devices’ ADSP-21489-100 SHARC DSP operating at 250 MHz, 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 21489-100 is particularly well suited for low power applications. The USB port can operate independently to support USB bus powered enumeration requirements. The dspblok 21489-100 also includes a full speed USB transceiver. You can use the USB to upload DSP code via Danville's dspBootloader™.

The dspblok 21489-100 is a low cost version of our fourth generation SHARC based products. It is compatible with other fourth generation dspbloks engines such as our dspblok 21489 and dspblok 21469.

Development couldn't be easier. You can connect to an Analog Devices ICE using a Danville JTAG Adapter. Analog Devices has two development packages available: CrossCore Embedded Studio or Visual DSP++.

We are an authorized reseller of Analog Devices Visual DSP++, CrossCore Embedded Studio and In-Circuit Emulators (ICE). These are the tools we use to develop our software. Our engineers can help you decide which tools will best fit your needs.

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.
