Toshiba TC35661SBG Bluetooth Single-Chip Controllers

Toshiba TC35661SBG Bluetooth®
Single-Chip Controllers

Toshiba TC35661SBG Bluetooth® Single-Chip Controllers are highly integrated RFCMOS Bluetooth devices designed to support Bluetooth Classic (3.0+EDR) and the BT LE (low energy) 4.0 standard. TC35661SBG complies with the standard Bluetooth HCI interface and offers integration of stack and selected BT profiles on-chip. Using the WIFI coexistence interface, TC35661SBG supports the BT3.0-HS function. Bluetooth Qualification Body (BQB) qualified, TC35661SBG provide an easy way to integrate Bluetooth for various industrial, medical, and automotive applications.

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.

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 functionality 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.

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 boot loaded 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.
