– The new sensor hub IC with Bluetooth® v4.1 –

TOKYO – Toshiba Corporation (TOKYO: 6502) today announced the launch of "TZ1041MBG", an application processor for wearable devices, the latest addition to its ApP Lite™ family TZ1000 series of solutions for the Internet of Things (IoT), first released in March 2014. Sample shipments will start in October and mass production is scheduled for January 2016.

The TZ1041MBG meets the increasing market demand for IoT devices that can support multiple external sensors, providing a versatile communication environment that makes use of the extended hub features of Bluetooth.

The new processor incorporates a Bluetooth v4.1 controller and processor, capable of capturing data from external sensors connected via various I/Os, such as I2C, UART, SPI and ADC, and it also incorporates flash memory to save data.

Data processing and storing of multiple sensing targets required for IoT devices are executable simultaneously by the new processor. In addition, TZ1041MBG can perform as a Bluetooth hub for collecting, processing and storing data, while its automatic reconnection function improves the operating efficiency and usability of the user system by using Low Duty Cycle Directed Advertising[Note].

Like other TZ1000 series devices, TZ1041MBG integrates a low power design feature that allows it to change supply voltage in response to the processor frequency. This makes it suitable for wearable products that require long operating hours.

Toshiba also supports sophisticated software algorithms for TZ1000 series, such as Activity Monitoring, PPG (Photoplethysmography) Monitoring and ECG (electrocardiography) Monitoring, which provides a total system solution for wearable products.

Key Features

Bluetooth v4.1 compliant

Integration of Bluetooth Smart controller and RF circuit allows transfer of raw and processed data to external devices, such as smartphones and tablets, enables:

  • Data collection, processing and storage, as a hub for Bluetooth communication devices
  • Low Duty Cycle Directed Advertising with automatic reconnection function
Low power design

Significantly reduces power consumption during operation; suitable for long hours of collecting and monitoring data as a sensor hub.

Communication function, memory and processor integrated in one package

Functions required for IoT devices are integrated into a single package, securing smaller system design.

Embedded ARM® Cortex®-M4F processor

The high performance ARM Cortex-M4F with DSP and floating point processing unit can collect  and process data from multiple external sensors.

High resolution ADCs

Integrates a 24-bit high resolution ΔΣADC with high speed switches connecting to three input channels. Capable of meeting the challenge of accurately measuring biomedical signals, such as the pulse and the heart’s electrical signal.


Wearable devices, such as activity monitoring products, smart watches, bracelet and glasses-type devices, and IoT devices.
