This Wi–Fi single– chip device provides a high level of integration with dual–stream IEEE 802.11ac MAC/baseband/radio, Bluetooth 4.1, and FM radio receiver. In IEEE 802.11ac mode, the WLAN operation supports rates of MCS0–MCS9 (up to 256 QAM) in 20 MHz, 40 MHz, and 80 MHz channels for data rates up to 867 Mbps. In addition, all the rates specified in IEEE 802.11a/b/ g/n are supported. Included on–chip are 2.4 GHz and 5 GHz transmit power amplifiers and receive low noise amplifiers. For the WLAN section, several alternative host interface options are included: an SDIO v3.0 interface that can operate in 4b or 1b modes, a high-speed inter-chip (HSIC) interface, and a PCIe v3.0 compliant interface running at Gen1 speeds. For the Bluetooth section, host interface options of a high-speed 4-wire UART and USB 2.0 full-speed (12 Mbps) are provided. The BCM4354 uses advanced design techniques and process technology to reduce active and idle power, and includes an embedded power management unit that simplifies the system power topology. In addition, the BCM4354 implements highly sophisticated enhanced collaborative coexistence hardware mechanisms and algorithms that ensure that WLAN and Bluetooth collaboration is optimized for maximum performance. Coexistence support for external radios (such as LTE cellular and GPS) is provided via an external interface. As a result, enhanced overall quality for simultaneous voice, video, and data transmission on a handheld system is achieved.
