dspblok 21489-100 - Analog Devices ADSP-21489-100 SHARC DSP Module
The dspblok™ 21489-100 is a highly integrated DSP module that incorporates an Analog Devices’ ADSP-21489-100 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 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 is a low-cost version of our fourth generation SHARC based products. It is largely software and hardware compatible with other fourth-generation dspbloks engines such as our dspblok 21489 and dspblok 21469. We recommend using this module as a quick migration target and then moving to the dspblok 21565 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++.
