GENERAL DESCRIPT ION

The Broadcom® BCM4354 is a complete dual–band

(2.4 GHz and 5 GHz) 5G Wi–Fi 2 × 2 MIMO® MAC/

PHY/Radio System–on–a–Chip. 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.
