The Altera Cyclone IV FPGA Device Handbook provides an overview of device features, resources, packages, speed grades, architecture, I/O, memory interfaces…
The Cyclone IV FPGA family offers low‑cost, low‑power solutions for high‑volume applications. It is available in two variants: Cyclone IV E, which emphasizes minimal power and cost, and Cyclone IV GX, which adds integrated high‑speed transceivers up to 3.125 Gbps.
The handbook details device resources such as logic elements, embedded memory, multipliers, PLLs, and user I/O pins, as well as the architecture, I/O standards, clock management, external memory interfaces, configuration methods, and high‑speed transceiver features including PCI Express hard IP. This manual is written in Chinese.
