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.

FEATURES

? Single-band 2.4 GHz IEEE 802.11 b/g/n

? Integrated WLAN CMOS power amplifier with internal power detector and closed-loop power control

? Internal fractional-N PLL enables the use of a wide range of reference clock frequencies

? Supports IEEE 802.15.2 external 3-wire and 4-wire coexistence schemes to optimize bandwidth utilization with other co-located wireless technologies such as Bluetooth, Zigbee, or BT Smart.

? Supports standard interfaces SDIO v2.0 (50 MHz, 4-bit and 1-bit) and generic SPI (up to 50 MHz)

? Integrated ARM Cortex?-M3 CPU with on-chip memory enables running IEEE 802.11 firmware that can be field-upgraded with future features.

? Supports WMM?, WMM-PS, and Wi-Fi Voice Personal (upgradable to Voice Enterprise in the future)

? Security:

– Hardware WAPI acceleration engine
