Meet Your Power Goals with Ease

With 200K logic elements (LEs) and 8-Mbits of memory for less than 1/4 watt of static power consumption, this family sets the power standard. Manufactured on Taiwan Semiconductor Manufacturing Company's (TSMC's) low-power (LP) process technology, these FPGAs make it easy to meet your power budgets, be it for communications equipment, handheld consumer products, or software-defined radios.

Design Security

Cyclone® III LS FPGAs are the first to offer a suite of security features at the silicon, software, and intellectual property (IP) level on a low power, high functionality FPGA. This suite of security features protects your IP from tampering, reverse engineering, and cloning. Additionally, these devices enable you to introduce redundancy in a single chip using design separation, which reduces the size, weight, and power of your applications.

Complete Design Resources

To assure a smooth, successful design flow, and to make it possible for you to turn your ideas into revenue quicker than ever before, Intel provides a complete Cyclone® III FPGA design environment. Take your designs from concept through production and reap the rewards of getting to market faster. With Cyclone® III FPGAs, the possibilities are unlimited.


With its unprecedented combination of low power, high functionality, and low cost, the Cyclone® III FPGA family broadens the number of high-volume, cost-sensitive applications that can benefit from an FPGA.
