Cypress Semiconductor Corporation 198 Champion Court San Jose, CA 95134-1709 408-943-2600 Document Number: 002-14912 Rev. *D Revised September 19, 2016 Not Recommended for New DesignsPreliminary Data Sheet BCM43236/BCM43236B 2.4 GHz/5 GHz IEEE802.11n MAC/PHY/Radio Chip GENERAL DESCRIPTION FEATURES The BCM43236/BCM43236B is a dual-band (2.4 GHz IEEE 802.11n-compliant and 5 GHz) IEEE 802.11n-compliant MAC/PHY/Radio 2.4 GHz and 5 GHz internal PA complete system-on-a-chip with 2.4 GHz and 5 GHz Two-stream spatial multiplexing up to 300 Mbps internal PAs. The device enables development of USB Uses on-chip OTP (One-Time Programmable) memory instead of SROM for substantial RBOM savings. 2.0- or HSIC-based IEEE 802.11n WLAN client and Supports MCS 015 and MCS 32 modulation and router subsystem solutions. The BCM43236/ coding rates. BCM43236B addresses all WLAN markets that deliver Supports 20 MHz and 40 MHz channels with optional high throughput and extended range of the Broadcom SGI. second-generation MIMO solution. With MIMO, Support for STBC in both TX and RX information is bidirectional over two or more antennas Greenfield, mixed mode, and legacy modes supported simultaneously using the same frequency band thus Full IEEE 802.11a/b/g legacy compatibility with providing greater range and increasing throughput, enhanced performance. while maintaining compatibility with legacy IEEE Supports one USB 2.0 host or one 480 MHz HSIC port. 802.11a/b/g devices. This is accomplished by a UART and JTAG interface, up to eight GPIOs. combination of enhanced MAC and PHY Supports up to 32 MB of serial flash memory. implementations including spatial transmitter/ ARM Cortex-M3 CPU core plus 256 KB ROM and receiver multiplexing modes and advanced DSP 448 KB RAM. techniques to improve receive sensitivity. 256 KB ROM supports driver ROMLIB of the latest 43236B Enhancements: driver for CPU host offload functionality. 256 KB ROM with WLAN driver mapped to support Supports Broadcoms OneDriver software. CPU host offload for low-end SoC platforms. Improved Supports WHQL certified drivers for Windows Vista 32- and 64-bit, Windows XP, and Windows 2000 radio for better band edge and output power operating systems for client applications. performance. Open Source Linux driver support. Supports Linux and VxWorks for access point and router applications. The BCM43236/BCM43236B architecture with its fully Comprehensive wireless network security support integrated dual-band radio transceiver supports 2 2 that includes WPA, WPA2, and AES encryption/ antennas for Layer 2 throughput of over 200 Mbps. decryption coupled with TKIP and IEEE 802.1X State-of-the-art security is provided by industry support. standardized system support for WPA, WPA2 (IEEE BCM43236/BCM43236B package: 10 mm x 10 mm 802.11i), and hardware-accelerated AES encryption/ 88-pin QFN decryption, coupled with TKIP and IEEE 802.1X APPLICATIONS support. Embedded hardware acceleration enables increased performance and significant reduction in host-CPU utilization in both client and access point USB 2.0 dongles configurations. The BCM43236/BCM43236B also HSIC media modules supports Broadcoms widely accepted and deployed WPS for ease-of-use wireless secured networks. 43236 43236B-DS103-R 5300 California Avenue Irvine, CA 92617 Phone: 949-926-5000 Fax: 949-926-5203 September 16, 2013 Not Recommended for New Designs
