Procurement Notes

Verify the specific suffix 'A' in the part number MAX32664GWEA+T against official datasheets to confirm support for finger-based sensors like the MAX30101/ MAX30102. Ensure compatibility with the intended host microcontroller via the slave I2C interface. Confirm RoHS compliance status through manufacturer documentation before integration into final products.

Selection Notes

Select this component when designing ultra-low power wearable systems requiring dedicated biometric processing. The WLP-16 package suits space-constrained designs. Verify that the required sensor interface matches the version A specifications for optical sensors. Consider the 570 nA standby current for battery-operated applications requiring extended life.

Part Context

The MAX32664 belongs to the Darwin low-power MCU family by Analog Devices / Maxim Integrated. It serves as a specialized sensor hub complementing other platform components like the MAX32630 ARM Cortex-M4F microcontrollers. This hub offloads sensor data processing, allowing the main processor to remain in low-power states while maintaining continuous biometric monitoring capabilities.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult Analog Devices technical support for cross-reference information regarding discontinued or alternative sensor hubs within the MAX326xx series.
