DataSheetFeature| Description | ・Important functions for wearable devices are integrated into a single, compact package, contributing to small system designs.
・The products integrate high-resolution ADC that can convert analog signals from external sensors, such as pulse wave and electrocardiogram, into digital data and deliver it to the internal processor.
・High-performance ARM® Cortex®-M4F with DSP and floating point processing unit enable a combination of data from multiple-sensors, both internal and external, to improve accuracy.
・Integration of a Bluetooth® LE controller and an RF circuit permits transfers of raw and processed data to external equipment, such as smart-phones and tablets. |
