Data Sheet
BCM43362
Single-Chip IEEE 802.11™ b/g/n MAC/Baseband/Radio + SDIO
GENERAL DESCRIPTION
The Broadcom® BCM43362 single-chip device
provides the highest level of integration for mobile
and handheld wireless systems, featuring integrated
IEEE 802.11™ b/g and handheld device class
IEEE 802.11n. It includes a 2.4 GHz WLAN CMOS
power amplifier (PA) that meets the output power
requirements of most handheld systems. An optional
external low-noise amplifier (LNA) and external PA
are also supported.
Along with the integrated power amplifier, the
BCM43362 also includes integrated transmit and
receive baluns, further reducing the overall solution
cost.
Host interface options include SDIO v2.0 that can
operate in 4b or 1b modes, and a generic gSPI mode.
Utilizing advanced design techniques and process
technology to reduce active and idle power, the
BCM43362 is designed to address the needs of
highly mobile devices that require minimal power
consumption and compact size. It includes a power
management unit that simplifies the system power
topology and allows for operation directly from a
rechargeable mobile platform battery while
maximizing battery life.
