Overview

This reference manual provides detailed functional and architectural descriptions for the NXP MCX A173 and MCX A174 microcontroller families. It covers the implementation of the Arm Cortex-M33 core, including the Nested Vectored Interrupt Controller (NVIC) and system memory mapping. The document outlines the bus and memory architecture, SRAM and Flash subsystem configurations, and integrated modules such as the Low Power Cache Controller (LPCAC), Flash Memory Module (FMU), and Error Recording (ERM). It also includes extensive documentation on signal multiplexing, port control (PORT), GPIO functionality, and system controller (SYSCON) register definitions required for hardware integration and firmware development.

Use Cases

  • Embedded firmware development for MCX A-series microcontrollers
  • Hardware system design and PCB layout planning
  • Peripheral configuration and signal multiplexing setup
  • Memory management and system bus optimization
  • Fault handling and error recording implementation
