i.MX RT500 Power Management
Detailed guide on power management for i.MX RT500 MCUs, including power rails, operating modes (Active to Full Powerdown), body bias modes, and SRAM power optimization.
Overview
This application note details power management strategies for the NXP i.MX RT500 crossover processor family. It describes internal power rails such as VDDCORE and VDD_AO1V8, along with their respective voltage ranges and load characteristics. The document defines five power modes: Active, Sleep, Deep Sleep, Deep Powerdown, and Full Powerdown. Key optimization techniques covered include SRAM partition management (array vs. periphery power gating), Body Bias modes (Normal, Reverse, and Forward), and clock management for PLLs and internal oscillators. It also explains hardware-based PMIC control using PMIC_MODE pins and pad voltage range configuration for reducing current consumption in low-power designs.
Use Cases
- Designing ultra-low power battery-operated devices
- Configuring power domains for crossover MCUs
- Managing memory power retention in sleep modes
- Implementing body biasing for frequency and power optimization
