The MAX32664 is part of a sensor hub family with embedded firmware and algorithms for wearables. It seamlessly enables customer-desired sensor functionality, which includes communicating with Maxim’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 device family interfaces to a microcontroller host through a fast-mode slave I2C interface for field updates as well as access to raw and processed sensor data.
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 C supports the MAX86140/MAX86141 for wrist-based applications. A master mode SPI interface for communication with sensors is 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 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.Learn more about the different versions ›
