The Arm Cortex-M302+ MCU is not a standalone brand but a microcontroller unit (MCU) based on ARM's Cortex-M architecture, designed by ARM Holdings, a British semiconductor and software design company. ARM licenses its technology to various manufacturers globally, which then produce MCUs like the Cortex-M302+ for embedded systems. These MCUs serve industries such as industrial automation, consumer electronics, automotive, and IoT, offering features like low power consumption, real-time processing, and connectivity. The Cortex-M302+ is tailored for applications requiring efficient performance in resource-constrained environments.
