AN13804: SLN-VIZNLC-IOT Power Consumption Features
Detailed analysis of power consumption and current measurements for the NXP SLN-VIZNLC-IOT smart access solution in Low-power and Normal operating modes.
Overview
This application note provides a detailed evaluation of power consumption for the SLN-VIZNLC-IOT crossover MCU-based facial recognition solution. It analyzes current draw across eight major system contributors, including the i.MX RT106F, LPC845 low-power MCU, PIR sensor, SDRAM, QSPI flash, camera, and LCD. The document defines performance metrics for Low-power mode (220 μA typical) and Normal mode (303 mA typical), providing hardware block diagrams, power supply architectures, and specific hardware modifications required for accurate current sensing. Measurement data is provided for individual components such as the Winbond SDRAM and flash memory to assist developers in optimizing energy efficiency for battery-powered smart lock and IoT applications.
Use Cases
- Smart lock power optimization
- Facial recognition access control design
- Battery life estimation for IoT devices
- Low-power motion detection system design
