Overview

This hardware design guide provides technical details and recommendations for developing systems based on the NXP i.MX RT500 crossover microcontroller family. Using the MIMXRT595-EVK evaluation kit as a reference, the document outlines power domain configurations (VDDCORE, VDDIO, VDD_AO1V8), external clock requirements, and debug/programming interface connections. It includes specific requirements for bulk and decoupling capacitor placement on the PCB, power-on sequencing guidelines, and layout recommendations for high-speed designs using ball-grid array (BGA) and eWLB packaging. The guide also details peripheral integration for components such as QSPI NOR Flash, PSRAM, eMMC, and audio codecs.

Use Cases

  • Developing custom hardware based on NXP i.MX RT500 microcontrollers
  • Configuring power supply rails and PMIC settings for MIMXRT595
  • Optimizing PCB layout and decoupling strategies for eWLB packages
  • Implementing external memory interfaces like FlexSPI and eMMC
  • Designing system-level power sequencing for crossover MCUs
