BCM43143 Advance Data Sheet
Introduction
Section 1: Introduction
The Broadcom® BCM43143 single-chip device provides the highest level of integration for wireless systems
with integrated IEEE 802.11b/g/n (MAC/PHY/radio). It provides a small form-factor solution with minimal
external components to drive down the cost for mass volumes and allows for wireless media client flexibility in
size, form, and function.
