Product Details
The MAX32664 is a sensor hub family with embedded firmware and world-class algorithms for wearables. It seamlessly enables customer-desired sensor functionality, including communication with Analog Devices' optical sensor solutions and delivering raw or calculated data to the outside world. This is achieved while keeping overall system power consumption in check. The device family interfaces to a microcontroller host through a fast-mode slave I2C interface for access to raw and processed sensor data as well as field updates. A firmware bootloader is also provided.
The MAX32664 Version A supports the MAX30101/MAX30102 high-sensitivity pulse oximeter and heart-rate sensor for wearable health for finger-based applications. A master mode I2C interface for communication with sensors is provided.
The MAX32664 Version B supports the MAX86140/MAX86141 for wrist-based applications. A master mode SPI interface for communication with sensors is provided.
The MAX32664 Version C supports the MAX86140/MAX86141 for wrist-based applications and MAXM86161 for ear-based applications. The device provides either a master mode SPI or an I2C interface for communication with sensors.
The MAX32664Version D supports the MAX30101/MAX30102 high-sensitivity pulse oximeter and heart-rate sensor for wearable health for finger-based applications. A master mode I2C interface for communication with sensors is provided. Version D also supports estimated blood pressure monitoring.
The wearable algorithms in the MAX32664 sensor hub support a directly connected accelerometer. They also allow feeding of X, Y, and Z samples from a host-connected accelerometer. This architecture provides robust detection and compensation of motion artifacts in captured samples.
The tiny form factor 1.6mm x 1.6mm WLP or 3mm x 3mm TQFN allows for integration into extremely small application devices.
