MAX32664GWEA+

Overview

The MAX32664GWEA+T is a biometric sensor hub from Analog Devices / Maxim Integrated, designed for wearable health monitoring applications. It operates on a 1.8 V supply voltage with a maximum input resistance of 10.5 kOhms. The device functions within a temperature range of -40°C to +105°C and consumes 570 nA of operating power current. It is housed in a WLP-16 package suitable for surface mount installation. This component serves as a fixed-function microcontroller with a bootloader and encryption capabilities, integrating with sensors such as optical heart rate monitors and analog front ends.

Feature Summary

• Fixed-function microcontroller architecture optimized for biometric sensing tasks
• Integrated bootloader and encryption features for secure firmware management
• Ultra-low power consumption suitable for battery-operated wearable devices

Applications

• Wearable electrocardiogram (ECG) monitoring systems
• Optical heart rate and pulse oximetry tracking devices
• Body temperature measurement wearables

Procurement Notes

Verify the specific suffix 'T' when ordering, as it indicates tape-and-reel packaging, which differs from the standard '+T' designation found in some distributor listings. Confirm RoHS compliance details directly with the manufacturer or authorized distributors, as environmental certifications may vary by production batch. Ensure the WLP-16 footprint matches your PCB design constraints before finalizing procurement.

Selection Notes

Select this component when designing compact wearable health devices requiring low-power sensor data processing. It is appropriate for systems integrating optical sensors like the MAX86141 and AFEs like the MAX30001. Consider the WLP-16 package size for space-constrained layouts. Verify that the 1.8 V operating voltage aligns with your system's power domain requirements.

Part Context

The MAX32664 is part of the Darwin series of ultra-low-power ARM Cortex-M4F microcontrollers from Analog Devices / Maxim Integrated. It is specifically engineered as a sensor hub to offload processing tasks from main application processors in wearable health platforms. This role allows it to manage multiple sensors efficiently while maintaining minimal power usage.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other members of the MAX326xx series for potential compatibility, ensuring that pinout, memory, and peripheral configurations match the original design requirements.
