Cyclone III LS FPGA Development Kit

from Intel (formerly Altera)

Intel's Cyclone® III LS FPGA Development Kit combines the largest density, low-power FPGA available with a complete suite of security features implemented at the silicon, software, and intellectual property (IP) levels. These security features provide passive and active protection of your IP from tampering, reverse engineering, and counterfeiting.

  1. Buyer represents that it is a product developer, software developer or system integrator and acknowledges that this product is an evaluation kit that is not FCC authorized, is made available solely for evaluation and software development, and may not be resold.
  2. You can purchase optional high-speed mezzanine card (HSMC) interface-compatible daughtercards, adapters, or cables to use with this development kit.

Cyclone III LS FPGAs and 8-, 16-, 32-Bit Soft IP Processors

Cyclone III LS FPGAs, when combined with embedded processor IP cores, are perfectly suited to function as embedded processors or microcontrollers. Check out the other Cyclone III FPGA-based kits bundled with and targeted for Nios® II embedded processing applications.

HSMC Interface

Intel developed the specification for the HSMC, which is based on the Samtec mechanical connector, to define and standardize the interface between optional daughtercards and host boards. This specification outlines both the electrical and mechanical properties of the interface between daughtercard and host. You can also create your own HSMC interface-compatible daughtercards.
