3 / 140 page Revision History BCM88335 Data Sheet Broadcom® September 23, 2015 • 88335-DS100-R Page 2 BROADCOM CONFIDENTIAL FEATURES FEATURES IEEE 802.11x Key Features • IEEE 802.11ac compliant. • Single-stream spatial multiplexing up to 433.3 Mbps data rate. • Supports 20, 40, and 80 MHz channels with optional SGI (256 QAM modulation). • Full IEEE 802.11a/b/g/n legacy compatibility with enhanced performance. • TX and RX low-density parity check (LDPC) support for improved range and power efficiency. • Supports RX space-time block coding (STBC) • Supports IEEE 802.11ac/n beamforming. • On-chip power amplifiers and low-noise amplifiers for both bands. • Support for optional front-end modules (FEM) with external PAs and LNAs • Shared Bluetooth and WLAN receive signal path eliminates the need for an external power splitter while maintaining excellent sensitivity for both Bluetooth and WLAN. • Internal fractional nPLL allows support for a wide range of reference clock frequencies • Supports IEEE 802.15.2 external coexistence interface to optimize bandwidth utilization with other co-located wireless technologies such as LTE, GPS, or WiMAX • Supports standard SDIO v3.0 (including DDR50 mode at 50 MHz and SDR104 mode at 208 MHz, 4-bit and 1-bit), and gSPI (48 MHz) host interfaces. • Backward compatible with SDIO v2.0 host interfaces. • Integrated ARMCR4™ processor with tightly coupled memory for complete WLAN subsystem functionality, minimizing the need to wake up the applications processor for standard WLAN functions. This allows for further minimization of power consumption, while maintaining the ability to field upgrade with future features. On-chip memory includes 768 KB SRAM and 640 KB ROM. •OneDriver™ software architecture for easy migration from existing embedded WLAN and Bluetooth devices as well as future devices. Bluetooth Key Features • Complies with Bluetooth Core Specification Version 4.1 for automotive applications with provisions for supporting future specifications. • Bluetooth Class 1 or Class 2 transmitter operation. • Supports extended synchronous connections (eSCO), for enhanced voice quality by allowing for retransmission of dropped packets. • Adaptive frequency hopping (AFH) for reducing radio frequency interference. • Interface support, host controller interface (HCI) using a high-speed UART interface and PCM for audio data. • Supports multiple simultaneous Advanced Audio Distribution Profiles (A2DP) for stereo sound. • Automatic frequency detection for standard crystal and TCXO values. • Supports low energy host wake-up for long term system sleep capability. |
