2.4 GHz/5 GHz IEEE802.11n MAC/PHY/Radio Chip

GENERAL DESCRIPTION

FEATURES

The BCM43236/BCM43236B is a dual-band (2.4 GHz

and 5 GHz) IEEE 802.11n-compliant MAC/PHY/Radio

complete system-on-a-chip with 2.4 GHz and 5 GHz

internal PAs. The device enables development of USB

2.0- or HSIC-based IEEE 802.11n WLAN client and

router subsystem solutions. The BCM43236/

BCM43236B addresses all WLAN markets that deliver

high throughput and extended range of the Broadcom

second-generation MIMO solution. With MIMO,

information is bidirectional over two or more antennas

simultaneously using the same frequency band thus

providing greater range and increasing throughput,

while maintaining compatibility with legacy IEEE

802.11a/b/g devices. This is accomplished by a

combination of enhanced MAC and PHY

implementations including spatial transmitter/

receiver multiplexing modes and advanced DSP

techniques to improve receive sensitivity.

43236B Enhancements:

256 KB ROM with WLAN driver mapped to support

CPU host offload for low-end SoC platforms. Improved

radio for better band edge and output power

performance. Open Source Linux driver support.

The BCM43236/BCM43236B architecture with its fully

integrated dual-band radio transceiver supports 2 × 2

antennas for Layer 2 throughput of over 200 Mbps.

State-of-the-art security is provided by industry

standardized system support for WPA™, WPA2™ (IEEE

802.11i), and hardware-accelerated AES encryption/

decryption, coupled with TKIP and IEEE 802.1X

support. Embedded hardware acceleration enables

increased performance and significant reduction in

host-CPU utilization in both client and access point

configurations. The BCM43236/BCM43236B also

supports Broadcom’s widely accepted and deployed

WPS for ease-of-use wireless secured networks.
