Toshiba has processor for wearable devices
1 min read
Toshiba's ApP Lite processor provides integrated sensing, data processing and wireless transmission for wearable devices such as activity monitors and smart watches.
The TZ1001MBG has 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 ARM Cortex-M4F with DSP and floating point processing unit allows combination of data from multiple sensors, both internal and external, to improve sensor accuracy.
The TZ1001MBG also integrates high resolution A/D converters that can convert analogue signals from external sensors, such as pulse wave and electrocardiogram (ECG) 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 A/D converter.
Toshiba says it will start sampling the processor in May, with mass production scheduled for September.
