The Arm Cortex-M40+ MCU is not a standalone brand but a microcontroller unit (MCU) architecture developed by Arm Holdings, a British semiconductor and software design company. Arm designs the Cortex-M series, including the Cortex-M40+, which is licensed to various manufacturers worldwide for integration into their own MCUs. These MCUs are widely used in industrial automation, consumer electronics, IoT, and automotive applications. The Cortex-M40+ is part of Arm's energy-efficient Cortex-M lineup, offering real-time processing capabilities for embedded systems. Companies like STMicroelectronics, NXP, and Texas Instruments produce MCUs based on Arm's Cortex-M cores, targeting industries requiring low-power, high-performance solutions.
