MAX32664GTGD+

MAX32664GTGD+ is an ultra-low power biometric sensor hub 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 server I2C interface for access to raw and processed sensor data as well as field updates. A firmware bootloader is also provided. The MAX32664 Version D supports the MAX30101/MAX30102 high-sensitivity pulse oximeter and heart-rate sensor for wearable health for finger-based applications. A host mode I2C interface for communication with sensors is provided. Version D also supports estimated blood pressure monitoring. Applications include wearable fitness, hearables, wearable medical, portable medical, mobile devices.
