Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Description:

The MAX32664GTGA ultra-low-power biometric sensor concentrator features embedded firmware and algorithms for wearables to seamlessly implement the sensor functions your customers require. These capabilities include communicating with Maxim optical sensor solutions and providing raw or calculated data to the outside world. These can be achieved without increasing the overall system power consumption.

MAX32664 version A supports the MAX30101 and MAX30102 sensors for finger-based wearable health applications. In addition, there is a host I2C interface for communicating with the sensor.

MAX32664 version B supports the MAX86140 and MAX86141 sensors for wrist-based applications. In addition, there is a host SPI interface for communicating with the sensor.

The MAX32664 version C supports the MAX86140 and MAX86141 sensors for wrist-based applications. In addition, there is a host SPI interface for communicating with the sensor.

The MAX32664 version D supports the MAX30101 and MAX30102 sensors for finger-based wearable health applications. In addition, there is a host I2C interface for communicating with the sensor.

The miniature package (1.6mm x 1.6mm WLP or 3mm x 3mm TQFN) allows the device to be integrated into ultra-small application devices.
