Overview
The Broadcom® BCM4354 single-chip device provides the highest level of integration for a mobile or handheld
wireless system, with integrated IEEE 802.11 a/b/g/n/ac MAC/baseband/radio, Bluetooth 4.1 + EDR (enhanced
data rate), and FM receiver. It provides a small form-factor solution with minimal external components to drive
down cost for mass volumes and allows for handheld device flexibility in size, form, and function.
Comprehensive power management circuitry and software ensure the system can meet the needs of highly
mobile devices that require minimal power consumption and reliable operation.
Figure 2 on page 18 shows the interconnect of all the major physical blocks in the BCM4354 and their
associated external interfaces, which are described in greater detail in the following sections.
