DSP-003 is a complete data acquisition and signal processing module with a very compact form factor.
It's small size, high processing speed and and low power consumption makes it an ideal choice when space, performance and power are issues.
DSP-003 is easily integrated into your product, you just have to provide power supply and an asynchronous serial port for communication.


Board interface:
A 40 pole HIROSE connector, contains power and most interface pins.
Code development is most easily done with Analog Devices VisualDSP development software. Analog Devices also have a number of emulators that connects to the DSP-003 JTAG connector. On board FLASH memories can be used for boot code and secondary code storage.
