Integrated processor helps downsize monitors and watches
Designed for wearable devices, the TZ1001MBG application processor from Toshiba Electronics Europe integrates sensing, data processing and wireless transmission into a single package. This reduces the mounting area and contributes to the downsizing of items such as activity monitors – used to help prevent lifestyle diseases, promote exercise and improve nutrition – smart watches and bracelet- and glasses-type devices
The device features an accelerometer to measure motion, a processor to handle the data acquired by the sensor, 8Mbit flash memory to store data, as well as RF circuitry and a Bluetooth low energy controller that supports low power communication.
A 48MHz high-performance ARM Cortex-M4F with DSP and floating-point processing unit allows combination of data from multiple sensors, internal and external, to improve sensor accuracy.
The product integrates high-resolution ADCs that can convert analogue signals from external sensors, such as pulse wave and electrocardiogram devices, into digital data, and deliver it to the internal processor. Transfer of raw and processed data to external equipment, such as smartphones and tablets is supported through the following I/O protocols USB, SPI, I2C, UART, 12bit ADC, 24bit Delta-Sigma ADC.
Sample shipments start in May, with mass production scheduled for September.
