Security embedded Bluetooth SoC support iBeacon

The new Bluetooth Smart system-on-a-chip (SoC) from Broadcom features RSA 4000 bit encryption and decryption support protecting the devices from critical security threats and to security-code the data during transfer.

The BCM20737 chip support Apple's iBeacon technology which Bluetooth Low Energy and geofencing to provide apps micro-location awareness, such as trail markers in a park, exhibits in a museum, or product displays in stores. Using iBeacon features smartphones they can find car keys, which are embedded with low-power transmitter.

The WICED Smart SoC also includes native support for A4WP Rezence wireless charging.

"Broadcom continues to build on its WICED success by tackling privacy concerns and keeping data safe with our new Bluetooth Smart chip," said Brian Bedrosian, Broadcom Senior Director, Embedded Wireless, Wireless Connectivity. "In addition, support for iBeacon is critical to Broadcom as the technology has seen strong adoption and is quickly gaining momentum in retail stores, sports venues, airports and more. By delivering top-shelf security and support for iBeacon, we are accelerating product development for our customers so that they can focus on creating the next wave of innovative applications in the evolving Internet of Things ecosystem."

"Advanced security in Bluetooth chips is becoming increasingly important to protect products from being hacked and to encrypt data being sent between products," said Philip Solis, Research Director, ABI Research. "2.7 billion Bluetooth-enabled products will ship this year - 20 percent more than 2013 - as more people connect accessories to mobile devices and PCs. Broadcom's Bluetooth Smart product can help reduce the risks these connections pose to consumers."

Key Features of the WICED Smart Chip as provided by Broadcom:
Encryption, decryption, certificate signing, verification and various algorithms for increased privacy
Support for iBeacon technology
Support for A4WP Rezence wireless charging
Integrated software to enable direct connect to NFC tag
Support for up to eight simultaneous master/slave connections
Support for audio over Bluetooth Smart enables voice capabilities for toys, remotes and more
Highly integrated ARM Cortex M3 applications processor for reduced solution size and cost
Superior receiver sensitivity for maximized range and coverage for Bluetooth peripherals
On-chip, multi-channel ADC for measuring sensor inputs, battery level and more
Onboard stack with many profiles embedded, eliminating the need for an external stack
Support for universal asynchronous receiver/transmitter (UART), serial peripheral interface (SPI) and Broadcom serial control interfaces for communication to external nonvolatile memories, peripheral integrated circuits (ICs) and sensors

Availability: The Broadcom BCM20737 is currently sampling with evaluation boards (EVBs) and software development kits (SDKs).

Broadcom Corporation has also introduced two new Bluetooth Smart systems-on-a-chip (SoCs) the BCM20734 and BCM20738 for peripherals.

Key Features of BCM20734 as given by Broadcom includes:
BCM20734 is the industry's first dual-mode chip that enables keyboards and mice to interact with computing platforms over either Bluetooth Smart or Bluetooth Classic
BCM20734 integrates ADC support for voice search capability and reduces the BOM for OEMs
BCM20738 offers OEMs a low-cost solution for single-mode Bluetooth Smart devices
BCM20734 and BCM20738 do not require a second crystal to stay connected during longer periods of device inactivity for additional reduction in system cost
BCM20734 and BCM20738 application development kits (ADKs) enable developers to create varied applications
BCM20734 and BCM20738 support Windows and Android host devices

The Broadcom BCM20734 and BCM20738 Bluetooth Smart chips, reference designs and ADKs are currently sampling with customers.
