Preliminary Data Sheet
BCM43236/BCM43236B
2.4 GHz/5 GHz IEEE802.11n MAC/PHY/Radio Chip
GENERAL DESCRIPTION
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.
