Broadcom Corporation was an American fabless semiconductor company that made products for the wireless and broadband communication industry.

Another large market is hardware for switches: some vendors offer switching equipment based on Broadcom hardware and firmware (e.g.

Dell Power Connect classics) while other well-known vendors do use the Broadcom hardware but write their own firmware.

These are So C devices with a Cortex R4 for processing the MAC and MLME layers and a proprietary Broadcom processor for the 802.11 physical layer.

In April 2017, Google's Project Zero investigated Broadcom's So C Wi Fi stack and found that it lacked "all basic exploit mitigations - including stack cookies, safe unlinking and access permission protection," allowing "full device takeover by Wi-Fi proximity alone, requiring no user interaction." Since the release of the 2.6.26 kernel some Broadcom chips have kernel support but require external firmware to be built.

Under the deal, Cypress acquires Broadcom's Io T products and intellectual property for Wi-Fi, Bluetooth and Zig Bee connectivity, as well as Broadcom's WICED platform and SDK for developers.

The deal combined Broadcom's developer tools and connectivity technologies for Io T devices with Cypress' own programmable system-on-a-chip (So C) products that provide memory, computing and graphics processing for low-power devices.

Major customers include Apple, Hewlett-Packard, Motorola, IBM, Dell, Asus, Lenovo, Linksys, Logitech, Nintendo, Nokia, Nortel(Avaya), Ti Vo, Tenda and Cisco Systems.

In September 2011, Broadcom shut down its digital TV operations.

The latest Broadcom Trident ASIC is used in many high-speed 10Gb switches from the largest switch-vendors such as Cisco Nexus switches running NX-OS, Video Core is the GPU found on some systems-on-a-chip (So C)s by Broadcom, the most widely known one being the BCM2835 containing Video Core IV found in the Raspberry Pi. Broadcom "BCM43" series chips provide Wi Fi support in many Android and i Phone devices.

Models include the BCM4339 used in phones such as the Nexus 5 (2013) and the BCM4361 used in the Samsung Galaxy S8 (2017).

According to the Raspberry Pi Foundation, this made it "the first ARM-based multimedia So C with fully functional, vendor-provided (as opposed to partial, reverse-engineered) fully open-source drivers", although due to substantial binary firmware code which must be executing in parallel with the operating system, and which executes independently and prior to loading of the operating system, this claim has not been universally accepted.
