Analog Devices / Maxim Integrated MAX32664 Ultralow Power Biometric Sensor Hub
Analog Devices Inc. MAX32664 Ultralow Power Biometric Sensor Hub features embedded firmware and algorithms for wearables and seamlessly enables customer-desired sensor functionality. This functionality includes communication with ADI's 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 MAX32664 Version A supports the MAX30101 and MAX30102 sensors 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 and MAX86141 sensors for wrist-based applications. A master mode SPI interface for communication with sensors is provided.
The MAX32664 Version C supports the MAX86140 and MAX86141 sensors for wrist-based applications. A master mode SPI interface for communication with sensors is provided.
The MAX32664 Version D supports the MAX30101 and MAX30102 sensors for wearable health for finger-based applications. A master mode I2C interface for communication with sensors is provided.
The tiny form factor (1.6mm x 1.6mm WLP or 3mm x 3mm TQFN) allows for integration into extremely small application devices.
