MAX32664GTGC+

MAX32664GTGC+ 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 C supports the MAX86140/MAX86141 for wrist-based applications and MAXM86161 for ear-based applications. The device provides either a host mode SPI or an I2C interface for communication with sensors. Applications include wearable fitness, hearables, wearable medical, portable medical, mobile devices.
