    Open Tool

    Analog Filter Wizard

    Use the Analog Filter Wizard to design low-pass, high-pass, or band-pass filters with actual op amps in minutes. As you progress through the design process, you can observe the characteristics of your filter design from ideal specifications to real world circuit behavior. Quickly evaluate the tradeoffs in op amp specifications - including gain-bandwidth, noise, and supply current – to determine the best filter design for your requirements.

    Open Tool

    Analog Photodiode Wizard

    Use Photodiode Wizard to design a transimpedance amplifier circuit to interface with a photodiode. Select a photodiode from the library included in the tool, or enter custom photodiode specifications. Quickly observe tradeoffs between Bandwidth, Peaking (Q), and ENOB/SNR. Modify circuit parameters, and immediately see results in plots for pulse response, frequency response, and noise gain.

Product Details

The ADSP-SC589 EZ-KIT Lite and EZ-Board® are evaluation systems for the ADSP-SC58x family of SHARC® processors. The ADSP-SC589 processor is based on the SHARC+™ core dual processor with the arm® Cortex-A5™ processor core and is designed for a wide array of markets, from automotive and pro-audio to industrial-based applications that require high floating-point performance. The EZ-Board is shipped with all of the necessary hardware—you can start the evaluation immediately. The package contains the standalone evaluation board, CE-approved power supply, and USB cable. The EZ-KIT Lite® version ships with an EZ-Kit license for CrossCore® Embedded Studio (CCES) and the ICE-1000 emulator, while the EZ-Board version requires the customer to provide an ICE-1000 or ICE-2000 emulator. The EZ-Kit license gives the user a full, subscription based license to use CCES with only the ADSP-SC589 EZ-KIT Lite evaluation board.


Expansion Interface III connectors are provided for interfacing with additional extender boards to provide LCD, camera, video, and audio. Traditional mechanical switches for changing the board's factory setup have been removed in favor of I2C controlled software switches. The only remaining mechanical switches are the boot mode switch, JTAG configuration switches, and push buttons.


The evaluation board is designed to be used in conjunction with the CrossCore® Embedded Studio (CCES) development tools to test capabilities of the ADSP-SC58x processors. The development environment aids advanced application code development and debug, such as:

  • Create, compile, assemble, and link application programs written in C++, C, and assembly
  • Load, run, step, halt, and set breakpoints in application programs
  • Read and write data and program memory
  • Read and write core and peripheral registers
