MAX32663AGTGFS+

Sensor And Detector Interfaces Overview

The MAX32663AGTGFS+ is an ultra-low power biometric sensor hub featuring embedded HeartKey ECG algorithms. It operates on a single supply voltage ranging from 1.71V to 3.63V, with a typical system clock frequency of 96MHz and an RTC input frequency of 32.768kHz. The device supports I2C communication at up to 400kHz and SPI master operation at 48MHz. It provides comprehensive health metrics including heart rate, heart rate variability, stress level index, energy expenditure, and user identification. The component is housed in a 24-pin TQFN-EP package measuring 3mm x 3mm.

Sensor And Detector Interfaces Procurement Notes

Verify the specific ordering suffix to confirm the firmware version (FS, W, or UI) required for your application. Ensure the package type matches the design footprint. Confirm RoHS compliance status if necessary for regulatory requirements. Check for future product availability notices as some variants may be subject to factory confirmation.

Sensor And Detector Interfaces Selection Notes

Select the FS version for complete access to all HeartKey algorithms including user identification. Choose the W version if security features are unnecessary to potentially optimize for specific use cases. Consider the TGTS+ suffix for tape and reel packaging if high-volume assembly is planned. Verify compatibility with the MAX30003 AFE for optimal integration.
