Ultra-Low Power  
MAX32664  
Biometric Sensor Hub  
General Description  
Benefits and Features  
The MAX32664 is a sensor hub family with embedded  
firmware and world-class algorithms for wearables. It  
seamlessly enables customer-desired sensor functionali-  
ty, 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  
● Biometric Sensor Hub Enables Faster Time to Market  
● Finger-Based (Version A) Algorithms Measure:  
• Pulse Heart Rate  
• Pulse Blood Oxygen Saturation (SpO )  
2
● Wrist-Based (Version B) Algorithm Measures:  
• Pulse Heart Rate  
● Wrist-Based or Ear-Based (Version C) Algorithms  
Measure:  
• Pulse Heart Rate  
2
slave I C interface for access to raw and processed sen-  
sor data as well as field updates. A firmware bootloader is  
also provided.  
• Pulse Blood Oxygen Saturation (SpO )  
2
● Finger-Based (Version D) Algorithms Measure:  
• Pulse Heart Rate  
The MAX32664 Version A supports the MAX30101/  
MAX30102 high-sensitivity pulse oximeter and heart-rate  
sensor for wearable health for finger-based applications.  
• Pulse Blood Oxygen Saturation (SpO )  
2
• Estimated Blood Pressure  
2
A master mode I C interface for communication with sen-  
sors is provided.  
● Both Raw and Processed Data Are Available  
● Basic Peripheral Mix Optimizes Size and Performance  
The MAX32664 Version B supports the MAX86140/  
MAX86141 for wrist-based applications. A master mode  
SPI interface for communication with sensors is provided.  
2
• One Slave I C for Communication with a Host  
Microcontroller  
2
• One Master I C for Communication with Sensors  
The MAX32664 Version C supports the MAX86140/  
MAX86141 for wrist-based applications and MAXM86161  
for ear-based applications. The device provides either a  
(Versions A, C, and D)  
• One Master SPI for Communication with Sensors  
(Versions B and C)  
2
master mode SPI or an I C interface for communication  
• 32.768kHz RTC  
with sensors.  
• FIFO Provides Minimal Host Interaction  
• Bootloader Facilitates Secure, Authenticated  
Firmware Upgrades  
The MAX32664 Version D supports the MAX30101/  
MAX30102 high-sensitivity pulse oximeter and heart-rate  
sensor for wearable health for finger-based applications.  
2
A master mode I C interface for communication with sen-  
sors is provided. Version D also supports estimated blood  
pressure monitoring.  
The wearable algorithms in the MAX32664 sensor hub  
support a directly connected accelerometer. They also al-  
low feeding of X, Y, and Z samples from a host-connected  
accelerometer. This architecture provides robust detection  
and compensation of motion artifacts in captured samples.  
The tiny form factor 1.6mm x 1.6mm WLP or 3mm x 3mm  
TQFN allows for integration into extremely small applica-  
tion devices.  
Applications  
● Wearable Fitness  
● Hearables  
● Wearable Medical  
● Portable Medical  
● Mobile Devices
