The MCX A26 devices are scalable microcontrollers in the MCX A Series ideal for PC accessories, motor control and connected embedded control.

MCX A26 integrates a 240 MHz Arm® Cortex®-M33 core, SmartDMA, FlexIO, dual FlexPWM modules and up to two 16-bit ADCs to support responsive real-time control and flexible data handling. Full-speed USB, dual CAN FD, I3C and support for 4x 44-segment LCD displays help developers combine performance, connectivity and human-machine interface (HMI) integration in a single MCU platform, while memory options up to 1 MB Flash and 256 kB RAM support scalable embedded designs.

The MCUXpresso Developer Experience provides software tools, application examples and expansion resources to support development, including the Expansion Board Hub (EBH) for add-on boards and the Application Code Hub (ACH) for software examples, with evaluation available through the FRDM-MCXA266 development boards to simplify prototyping and feature exploration.
