Data Sheet
BCM88335
Single-Chip 5G Wi-Fi IEEE 802.11ac MAC/Baseband/
Radio with Integrated Bluetooth 4.1 for
Automotive Applications
GENERAL DESCRIPTION
The Broadcom^® BCM88335 single-chip device
provides the highest level of integration for
Automotive In-Vehicle Infotainment connectivity
systems with integrated single-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
433.3 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 amplifiers, and receive
low-noise amplifiers. Optional external PAs, LNAs,
and antenna diversity are also supported.
The BCM88335 offers an SDIO v3.0 interface for high
speed 802.11ac connectivity. The Bluetooth host
controller is interfaced over a 4-wire high speed
UART and includes PCM for audio.
GENERAL DESCRIPTION
The BCM88335 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 BCM89335 is tested to AECQ100 environmental
stress guidelines and manufactured in ISO9001 and
TS16949 certified facilities.
The BCM88335 implements highly sophisticated
enhanced collaborative coexistence hardware
mechanisms and algorithms, which ensure that
WLAN and Bluetooth collaboration is optimized for
maximum performance. In addition, coexistence
support for external radios (such as LTE cellular,
GPS, and WiMAX) is provided via an external
interface. As a result, enhanced overall quality for
simultaneous voice, video, and data transmission is
achieved.
