STMicroelectronics ST1VAFE3BXTR Biometric Sensor, 12-Pin, LGA

The STMicroelectronics Biosensor embedding a vAFE channel to detect bio potential signals and a high-performance 3-axis digital accelerometer for motion tracking. The device has been designed with a very compact, low-noise, and low-power vAFE with configurable input impedance. The vAFE enables reading analog signals that are complementary to motion signals. The vAFE and motion signals are intrinsically synchronous, so the result is a unique context-aware edge analysis, thus low power and with the minimum possible latency.
