Toshiba Bluetooth IC With Integrated DSP Targets Automotive Audio Streaming And Hands-Free Subsystems

February 26, 2015

 

Built-in supporting circuitry and inclusion of full software stack and profiles saves on system bill-of-materials costs and helps lower time to market

Toshiba TC35668

SAN JOSE, Calif., — Toshiba America Electronic Components, Inc. (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, today announced a new system IC that combines full Bluetooth® operation with audio processing capabilities and supporting circuitry. The TC35668IXBG offers a highly integrated solution for automotive hands-free and audio streaming subsystems. Suitable for integration by car OEMs and for after-sales automotive market audio systems, the new IC can also form the basis of a subsystem such as a wireless speaker.

Deepak Mithani, senior director, Mixed-Signal Business Unit, System LSI Group at TAEC, noted, "Consumer demand for the latest automotive technologies continues to grow, hand-in-hand with the need to make these capabilities as safe as possible. This new IC allows developers to build hands-free functionality at the system level, harnessing the power of Toshiba’s proven ARM® processor-based cores together with our expertise in Bluetooth-enabled technology."

The TC35668IXBG features three core elements: an ARM Cortex®-M3 based system core; a Bluetooth core with 52MHz ARM7TDMI-S®; and a 208MHz CEVA TeakLite-III® DSP core. The Bluetooth core combines a transceiver, antenna switch, balun, low noise amplifier and power amplifier. Toshiba has integrated not only the standard Bluetooth HCI (host controller interface) hardware and software but also a full software stack and a set of 14 classic and BLE GATT profiles, which are Bluetooth SIG compliant. Stack and profiles are pre-certified and reside in ROM, and application code is stored in an external serial flash memory and executed from internal SRAM. This combination of hardware and software results in a very small bill of materials that can help companies minimize system size and cost, and allows a faster time-to-market due to proven embedded software.

In addition to full support for Bluetooth v4.0 with embedded stack, various Bluetooth Classic profiles and Bluetooth Low Energy (BLE) GATT profile, Toshiba has incorporated a DSP that allows for acoustic improvements inside a noisy environment, such as a car, and echo cancellation for hands-free systems. The signal processor is also capable of decoding audio content, including MP3 and AAC files. Another embedded MCU enables the execution of application software.

The TC35668IXBG is supplied in a compact 97-ball P-VFBGA package measuring 6.0 x 6.0 x 1.0mm. A trace UART interface is incorporated that aids system debugging and enables developers to tune the characteristics of the device for echo cancellation and noise reduction.

Availability

Sampling now, the TC35668IXBG is slated to begin mass production in Q3 2015.
