The ARM Cortex-M112+ MCU is not a standard or officially recognized model under ARM's Cortex-M series. ARM Holdings, a UK-based semiconductor and software design company, develops the Cortex-M series of microcontroller units (MCUs), which are widely used in embedded systems across industries like automotive, industrial automation, and consumer electronics. ARM's Cortex-M processors, including popular models like Cortex-M0, M3, and M4, are licensed to various manufacturers (e.g., STMicroelectronics, NXP) for integration into their MCUs. If 'Cortex-M112+' refers to a custom or niche variant, it may be a mislabeling or a proprietary modification by a specific manufacturer. For accurate details, refer to ARM's official documentation or authorized distributors like Radwell or Grainger for industrial-grade MCU solutions.
