MAX32663A
Ultra-Low Power ECG
Biometric Sensor Hub
Detailed Description
Three Different Versions of the MAX32663A
● Version FS (Full HeartKey Suite) includes all available ECG measurements in a single sensor hub.
• Heart Rate, Heart Rate Variability, Stress Level Index, Energy Expenditure, and User Identification
● Version W (Health and Wellness) excludes the security portion to aim applications where the security portion of a
design is not needed, and instead focuses on the health and wellness measurements.
• Heart Rate, Heart Rate Variability, Stress Level Index, and Energy Expenditure
● Version UI (User Identification) is ideal when you need a method of identifying users before giving access to your end
product.
• User Identification
Heart Rate (HR)
Heart rate provides one of the most common base insights into your body’s health. The HeartKey Heart Rate algorithm
is as accurate on dry electrodes as a medical Holter monitor using wet electrodes. When the signal quality is sufficient,
an estimated heart rate is displayed after three intervals with medical-grade accuracy available after nine intervals.
Heart Rate Variability (HRV)
HRV is a key indicator of heart health and is increasingly used as a metric for wellness as well. By calculating a
quantitative measurement into the autonomous nervous system (ANS), it can provide insight into a user's health,
including overtraining in athletes and as an input into stress measurements.
Physiological Stress
In the U.S. alone, stress is estimated to cost 2.6% of the US GDP, which is equivalent to $300 billion. The Stress
algorithm allows a user to monitor their state in real time and take appropriate action. The Stress algorithm calculates a
stress score between 0 to 100 on 30 interval windows, updating every 15 intervals.
Energy Expenditure (EE)
Obesity is a leading contributor to health issues in a variety of areas. In 2015/2016 it was estimated that one in three
adults in the USA were obese. One of the most effective ways of weight loss is through the tracking and management of
calories. The EE algorithm uses physiological metadata and the ECG to calculate the amount of energy a user is using
in real time.
HeartKey User ID
The HeartKey User ID uses your ECG to identify you, give early insight of cardiac conditions, protecting your
physiological data and personalizing wellness insights. Accuracy in real-world applications is 1:1000 and can be used as
part of a multimodal approach to improve system security. Subjects can be identified in less than five beats where there
is sufficient quality signal capture.
Interface to Host
2
The interface to the host is the I C interface The devices support one slave interface with an address of 0x55. The
features for this interface are as follows:
● One slave for communication with a host
● RESTART condition
● Fast mode: 400kbps
● Internal filter to reject noise spikes
● Receiver FIFO depth of 8 bytes
● Transmitter FIFO depth of 8 bytes
