MAX32664GTGD+

Overview

The MAX32664GTGD+T is a biometric sensor hub from Analog Devices/Maxim Integrated, packaged in a TQFN-24. It supports Version D algorithms for finger-based applications, measuring pulse heart rate, SpO2, and estimated blood pressure. The device interfaces with host microcontrollers via a fast-mode slave I2C port and connects to sensors using a master mode I2C interface. Key electrical parameters include a supply voltage range of 1.71V to 3.63V, a system clock frequency up to 96MHz, and an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrated firmware and algorithms for wearable health monitoring
• Supports finger-based pulse heart rate, SpO2, and blood pressure estimation
• Slave I2C interface for host communication and master I2C for sensor access
• Includes bootloader for secure firmware upgrades

Applications

• Wearable Fitness
• Wearable Medical
• Portable Medical
• Mobile Devices

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and RoHS compliance. Confirm availability status directly with authorized distributors as supply conditions may vary. Ensure the ordering information matches the required algorithm version for the intended application.

Selection Notes

Select this component for compact wearable designs requiring integrated biometric processing. Verify that the TQFN-24 package fits the mechanical constraints. Ensure the host system supports the required I2C protocols for data retrieval and control.

Part Context

This part belongs to the MAX32664 family of ultra-low power biometric sensor hubs. The GTGD suffix indicates the TQFN-24 package variant. Other versions in the series support different form factors like WLP or different sensor interfaces such as SPI.

Replacement Considerations

Check for other MAX32664 variants (e.g., GWEB) if a different package or sensor interface is needed. Verify compatibility with existing firmware and hardware layouts before substitution.
