Overview

This document details internal power measurements for the NXP i.MX 6ULL applications processor. It covers the analysis of key power supply domains including VDD_SOC_IN, VDD_HIGH_IN, and NVCC_DRAM. The note provides empirical data for specific use cases such as low-power modes (Deep-Sleep, System Idle), Dhrystone benchmarks at multiple clock frequencies (528 MHz, 800 MHz, 900 MHz), and 480P video playback. Additionally, it offers guidance on reducing power consumption through Dynamic Voltage and Frequency Scaling (DVFS), On-die termination (ODT) optimization for DDR3L/LPDDR2 memory, and software procedures for suspend states.

Use Cases

Power supply domain selection
Current drain measurement and analysis
Deep-Sleep mode configuration
Dhrystone benchmark performance testing
Video playback power optimization
DDR3L/LPDDR2 memory interface power tuning
