Toshiba ApP Lite™ IoT Processor supports Bluetooth® v4.1 functions

Toshiba America Electronic Components, Inc. said it has rolled out the newest addition to its TZ1000 series of ApP Liteâ„¢ processors targeting Internet of Things (IoT) applications.

Targeting smart wearable products, the TZ1041MBG was developed to meet 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 TZ1041MBG, like the other products in the TZ1000 series, integrates an ARM® Cortex®-M4F processor with 8Mbit Flash memory1 and Bluetooth functionality in a single package. Specifically, the new processor incorporates a Bluetooth v4.12 controller and processor capable of capturing data from external sensors connected via various I/Os (e.g., UART, I2C, SPI and ADC), and 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, the TZ1041MBG uses Low Duty Cycle Directed Advertising (LDCDA), a new function supported by Bluetooth v4.1 that enables automatic reconnection when a known device comes within the communication area covered by a hub. The TZ1041MBG can thus serve as a Bluetooth hub for collecting, processing and storing data, while the LDCDA function improves user system operating efficiency and usability.

The processor integrates a 24-bit high-resolution delta-sigma analog-to-digital converter (ADC) with high-speed switches connected to three input channels, enabling it to accurately measure biomedical signals such as pulse rate and the heart´s electrical activity. In addition, integration of the Bluetooth v4.1 controller and RF circuit allows transfer of raw and processed data to external equipment, such as smartphones and tablets.

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

Through proven commitment, lasting relationships and advanced, reliable electronic components, Toshiba enables its customers to create market-leading designs.
