dspblok 21489-100-ETH - Analog Devices ADSP-21489-100 SHARC DSP Module

The dspblok™ 21489-100+Ethernet is a highly integrated DSP module that incorporates an Analog Devices’ ADSP-21489 SHARC DSP operating at 400 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+Ethernet also includes a Microchip ATMega32U4 which functions as full-speed USB transceiver as well as additional GPIO. You can use the USB to upload DSP code via Danville's dspBootloader™.

The dspblok 21489-100+Ethernet includes a WIZnet W5100 Ethernet transceiver operating at 100Mb/s. Each module has a unique MAC address preassigned. The transceiver manages the TCP/IP stack so that the DSP is largely unburdened. You just add magnetics and a connector. Since the magnetics are external, you can also create Power over Ethernet (POE) targets for smart sensor applications.

The dspblok 21489-100+Ethernet replaces our dspblok 21489+Ethernet. The main difference is that the ethernet transceiver and USB interface has changed.  We recommend using this module as a quick migration target and then moving to the dspblok 21565+Ethernet as a more long term solution.

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++.
