MAX32664GWED+T

Overview

The MAX32664GWED+T is a biometric sensor hub from the MAX32664 family, designed for wearable applications. It integrates embedded firmware and algorithms to process data from optical sensors like the MAX86140/86141. The device features a 96MHz system clock and operates on a single supply voltage ranging from 1.71V to 3.63V. It communicates with host microcontrollers via a fast-mode I2C slave interface and connects to sensors using an SPI master interface. The component is housed in a 16-ball wafer-level package (WLP) measuring 1.6mm x 1.6mm.
