The MCX A35 devices are scalable mixed-signal microcontrollers in the MCX A Series designed for advanced motor control and high-performance embedded control.

MCX A35 integrates a 240 MHz Arm® Cortex®-M33 core, a mathematical acceleration unit (MAU) to improve performance in real-time motor control computations, SmartDMA, dual FlexPWM modules, up to 4 embedded OpAmps and four ADCs to support responsive control loops, fast math processing and accurate motor sensing. With up to 1 MB of Flash, up to 256 kB of RAM and rich serial peripherals, the MCX A35 helps developers combine processing performance, analog integration and efficient data movement in a single MCU platform.

The MCUXpresso Developer Experience provides software tools, application examples and expansion resources to support MCX A35 development with evaluation available through the FRDM-MCXA366 development board to simplify prototyping and feature exploration.
