NXP Semiconductors has introduced the i.MX RT1050, part of a new i.MX RT series of real-time applications processors.
The i.MX RT1050 is described as a crossover processor, bridging the gap between traditional microcontrollers and i.MX applications processors. It gives MCU users a means to gain valuable performance and integration improvements without sacrificing the ease-of-use of an MCU operating environment.
The high performance of the device’s 600MHz Arm® Cortex®-M7 core and its dedicated motor-control peripherals means that it can be used in demanding motor-system designs. For instance, it can:
• Implement Field-Oriented Commutation (FOC) control of four high-speed sensorless motors in a drone
• Control the servo motor actuators used in four-axis CNC milling, or control a 3D printer head with an additional motor for the 3D printing extruder
• Run FOC control of two sensorless motors while also controlling a camera and display preview
The peripheral set for these motor-control functions includes four flexible PWMs, two 12-bit ADCs, four quadrature timers, four quadrature encoders/ decoders, and four periodic interrupt timers.
Crossover processors are built using an applications processor’s chassis, and offer a high level of integration, enhanced security, and 2D and 3D graphics engines. But unlike a pure applications processor, they are powered by a low-power MCU core which runs a real-time operating system.
