BCM4330 Overview
Section 1: BCM4330 Overview
Overview
The Broadcom® BCM4330 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 (MAC/baseband/radio), Bluetooth 4.0 + EDR (enhanced
data rate), and FM transceiver. 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 shows the interconnect of all the major physical blocks in the BCM4330 and their associated external
interfaces, which are described in greater detail in the following sections.
