NXP Semiconductors latest general-purpose microcontroller family MCX

New microcontroller family MCX from NXP

The new microcontroller family MCX from NXP Semiconductors is a cutting-edge edge device based on Arm® Cortex®-M.

The core technology is common to each series, and it is designed to make maximum use of the MCU Expresso development environment, and past design assets such as LPC, Kinetis, and i.MXRT can be ported as-is to MCX, reducing the number of man-hours required for replacing design resources. can be minimized.

It is a microcontroller that balances overall system cost and energy efficiency while meeting the complex development requirements of next-generation edge applications such as power consumption, performance, security, and connectivity.
