Toshiba's Bluetooth® ICs provide proven high connectivity, stability and interoperability, allowing various application scenarios by using an HCI model with additional host CPU and ported Bluetooth stack/profile software, an integrated stack/profile concept with application on host MCUs, or a stand-alone configuration (no external host MCU) with bootable program code from external EEPROM.
The recent LSI TC35661SBG supports both the Bluetooth® classic standard up to BT3.0-EDR including a coexistence interface to WIFI solutions, and the new Bluetooth® Low Energy (LE) standard within the new standard BT4.0.
The integration of nearly all RF and peripherals components lowers the BoM significantly and eases PCB design.
Toshiba's hardware and software have undergone qualified Bluetooth® tests and have proven it´s interoperability to hundreds of mobile solutions in the marketplace.
The integration of stack and profiles offers an all-in-one Bluetooth® system solution and is currently available with profiles such as SPP, HID, or BLE GATT. Various application profiles (e.g. heart-rate, glucose-meter, battery sevice, find me etc.) according to BT LE standard are available, too.
Toshiba cooperates with partner companies to realize state-of-the-art ready-made module solutions for the industrial, medical or consumer market, which eases the adaption of this technology into systems and shortens Time-to-Market.

Bluetooth Module with TC35661 Bluetooth LSI available
The Toshiba Bluetooth® LSI TC35661SBG has been embedded - including it's SPP & BLE-GATT profile - into the Panasonic (PIDEU) module PAN1026. It is FCC/IC/CE certified. The embedded stack and profile were Bluetooth™ SIG approved through extensive BQB (Bluetooth™ Qualification Body) tests. The module is ideal for for wireless serial applications and all kind of BLE connectivity. System developers can make use of the Serial Port Profile and hook on their selected BLE profile onto BLE-GATT through the comfortable Toshiba API interface over UART. Read more... (pdf)

TC35661SBG HCI System Concept
The Bluetooth® HCI (host controller interface) model: the low layer stack (RF, LC, LM) runs on the TC35661SBG device (ROM or external flash memory). Through a UART or USB it is connected to an external host processor, which executes the upper Blueooth® stack (L2CAP, RFCOMM) and profiles. Beyond the upper stack the host processor runs the application software. This application processor may also run additional tasks such as middleware and multimedia functions. This concept is suitable for voice and data.
TC35661SBG Embedded Profile System Concept
The Embedded Profile model integrates both the lower and upper stack as well as some selected profiles in the TC35661SBG (ROM or external flash memory). The UART interface carries the data of a higher layer API. The whole Bluetooth® functionaly is managed by the Bluetooth® LSI. The host processor only handles the application data. Depending on the complexity of the application the host CPU performance requirement can be very minor. This concept is for data only. The Embedded Profile models for BT4.0 feature Smart Ready (dual mode) or Smart (BLE single mode) Bluetooth® marking.
TC35661SBG Stand Alone System Concept
TC35661 can be run without an additional host MCU for small applications. The application code gets stored into the attached EEPROM. After RESET the code is bootloaded into the embedded SRAM of TC35661-7xx/1xx and executed by the Bluetooth processor itself. This feature is available together with devices containing the Bluetooth stack with embedded SPP profile (-7xx) or HID profile (-1xx) in ROM. Toshiba uses commercial debugger software to allow evaluation of the application code.
