描述
The CL2440 is a powerful, highly integrated, 4x4 802.11ac Wave 2, 5GHz single chip implementing full 802.11ac Wave 2 functionality. The CL2440 integrates both a CPU and memory to run more of the wireless LAN functions on-chip, with no need for costly external memories. Designed for fit, the CL2440 comes in a compact 88-pin QFN enabling a full 4x4 high performance 802.11ac interface in a standard full-sized min PCIe card with the lowest power consumption.
