Description

The Broadcom® BCM4330 single chip device provides for the highest level of integration for a mobile or handheld wireless system, with integrated IEEE 802.11™ a/b/g and single-stream 802.11n (MAC/baseband/radio), Bluetooth® 4.0 + HS, and FM radio receiver and transmitter. It includes on-chip 2.4 GHz and 5 GHz WLAN CMOS power amplifiers that meet the output power requirements of most handheld systems while permitting an optional external power amplifier for higher output power applications, if required.

Specifications and features

• Single-band 2.4 GHz 802.11 b/g/n or dual band 2.4 GHz and 5 GHz 802.11 a/b/g/n (non simultaneous)
• Single stream 802.11n support for 20 MHz channels provides PHY layer rates up to MCS7 (72 Mbps) for typical upper-layer throughput in excess of 45 Mbps.
• Integrated CMOS power amplifiers with internal power-detectors and closed-loop power control can deliver greater than 18 dBm of linear output power (in 2.4 GHz band).
• PAs can be powered directly from VBAT, eliminating the need for a PALDO.
• Up to 8 RF control signals are available to support optional external PAs for higher output power and LNAs for enhanced sensitivity.
• Supports a single 2.4 GHz antenna shared between WLAN and Bluetooth.
• 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 three-wire coexistence scheme to optimize bandwidth utilization with other co-located wireless technologies such as GPS, WiMax, or UWB.
• Supports standard SDIO v2.0 (50 MHz, 4-bit and 1-bit), and gSPI (48 MHz) host interfaces.
• Alternative host interface supports HSIC (a USB 2.0 derivative for short-distance, on board connections).
• Integrated ARM® Cortex-M3 processor and on-chip 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.
• OneDriver™ software architecture for easy migration from existing embedded WLAN and Bluetooth devices as well as future devices.
• Bluetooth Core Specification Version 4.0 + HS compliant 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
• The FM unit supports HCI for communication, stereo analog input and output
• Low-power consumption improves battery life of handheld devices
• FM receiver: 65 MHz to 108 MHz FM bands; supports the European Radio Data Systems (RDS) and the North American Radio Broadcast Data System (RBDS) standards
• Supports multiple simultaneous Advanced Audio Distribution Profiles (A2DP) for stereo sound
• Automatic frequency detection for standard crystal and TCXO values
• FM transmitter: 65 MHz to 108 MHz bands; supports both RDS and the RBDS standards and programmable output power.
• Supports battery voltage range from 2.3V to 4.8V supplies with internal switching regulator
• Programmable dynamic power management
• 2 Kbit OTP for storing board parameters
• Package options:
  - 144 ball FCFBGA (6.5 mm x 6.5 mm, 0.5 mm pitch)
  - 133 ball WLBGA (4.89 mm x 5.33 mm, 0.4 mm pitch)
  - 225 bump WLCSP (4.89 mm x 5.33 mm, 0.2 mm pitch)
• Security:
  - WPA™- and WPA2™- (Personal) support for powerful encryption and authentication
  - AES and TKIP in hardware for faster data encryption and 802.11i compatibility
  - Reference WLAN subsystem provides Cisco® Compatible Extension- (CCX, CCX 2.0, CCX 3.0, CCX 4.0, CCX 5.0) certified
  - Reference WLAN subsystem provides Wi-Fi Protected Setup (WPS)
• Worldwide regulatory support: Global products supported with worldwide homologated design
