BCM89359
Single-Chip 5G WiFi IEEE 802.11ac 2×2 MAC/Baseband/
Radio with Integrated Bluetooth 4.1/RSDB for Automotive
Applications
GENERAL DESCRIPTION
GENERAL DESCRIPTION
The Broadcom® BCM89359 is a complete dual-band
(2.4 GHz and 5 GHz) 5G WiFi 2×2 MIMO MAC/PHY/
Radio System-on-a-Chip. This 5G WiFi single-chip
device provides a high level of integration with dual-
stream IEEE 802.11ac MAC/baseband/radio,
Bluetooth 4.1. 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 the 2.4 GHz and 5 GHz transmit
power amplifiers and receive low noise amplifiers.
The WLAN operation supports two fully simultaneous
SISO channels real simultaneous dual-band (RSDB).
The BCM89359 brings the latest mobile connectivity
technology to automotive infotainment, telematics,
and rear-seat entertainment. Offering Automotive
Grade 3 (–40°C to +85°C) temperature performance,
the BCM89359 is tested to AECQ100 environmental
stress guidelines and manufactured in ISO9001 and
TS16949-compliant facilities.
In addition, the BCM89359 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 automotive
systems is achieved.
For the WLAN section, several alternative host
interface options are included: an SDIO v3.0 interface
that can operate in 4b or 1b modes, high-speed 4-wire
UART, 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.
