BCM4704

The BCM4704 is a semiconductor integrated circuit developed by Broadcom Corporation. It is a System-on-a-Chip (SoC) designed primarily for wireless networking applications, specifically for use in wireless routers and access points. The chip integrates several key components necessary for network connectivity, including a central processing unit (CPU), a wireless local area network (WLAN) MAC (Media Access Control) and baseband processor, and a network interface controller (NIC).

The CPU within the BCM4704 is typically a MIPS-based processor, providing the computational power to run the router's operating system and manage network traffic. The integrated WLAN engine supports various Wi-Fi standards, allowing devices to connect wirelessly. The NIC component facilitates wired Ethernet connectivity, enabling traditional network connections.

The BCM4704 was a significant component in many consumer and small business networking devices during its time. Its integration of multiple functions onto a single chip helped reduce the complexity and cost of manufacturing wireless routers. While newer Broadcom chipsets have since been released with enhanced features and performance, the BCM4704 played a crucial role in the proliferation of Wi-Fi technology. Its architecture and capabilities were representative of the advancements in embedded system design for networking.
