Altera Cyclone® IV FPGAs

Altera Cyclone^® IV FPGAs extend the power- and cost-optimized Cyclone FPGA series that is engineered for very low cost and power consumption, making the devices ideal for high-volume, cost-sensitive applications across industries such as wireless, broadcast, industrial, and retail electronics. Cyclone IV devices are available in two variants: the Cyclone IV E (FPGA fabric and I/O optimized for low power and high functionality) and the Cyclone IV GX, which adds low-power 3.125Gbps transceiver inputs and outputs supporting multiple serial channel protocols and PCIe 1.0 x1/x2/x4 lane capabilities.

These Altera FPGAs provide a balance of simple logic, memory, DSP/AI compute engines, along with an abundance of general-purpose I/Os (GPIOs) and transceiver I/O to support efficient protocol bridging in power-sensitive, cost-sensitive, and high-volume applications. Providing power and cost savings, without sacrificing performance, along with a low-cost integrated transceiver option, Cyclone IV devices are ideal for low-cost, small-form-factor applications in the wireless, wireline, broadcast, industrial, consumer, and communications industries.

These FPGAs offer up to eight transceiver I/O channel pairs, and each transceiver channel pair consumes only 150mW, ensuring low-power operation even for high-speed serial I/O protocols. Additionally, the robust and configurable DSP capabilities make these devices capable of handling small AI workloads like Tiny ML and other convolutional neural networks, in addition to traditional DSP algorithms like FIR filters and FFTs used in image and signal processing.
