Introduction

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.

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.
