Brushed Motor Control



Brushed DC Motor Control with Z8 Encore!® Microcontrollers

Z8F0830/Z8F083A Microcontrollers

The Z8 Encore! Family offers several devices that meet the needs of universal and brushed DC motor control, along with basic fan control. The Z8 Encore!®-based Z8F0830 and Z8F083A devices are designed for these types of motors and include an optimized 8-bit eZ8 core, direct memory-to-memory arithmetic operation, a flexible Internal Precision Oscillator (IPO), and a fast ADC.


If your design requires more precision, the Z8F083A MCU takes all of the performance and key peripheral features of the Z8F0830 MCU and adds a more optimized peripheral set that specifically caters to applications that require faster response times. This enhanced Z8F083A peripheral set enables critical motor control loop operations, for example, that accommodate for features such as current and temperature monitoring that are crucial for motor control applications.


Both the Z8F0830 and Z8F083A Series devices are pin-for-pin compatible to allow you to select the best device for your application.


The Z8F0830 and Z8F083A Series MCUs are also suitable for digital power management, battery charging and environmental sensor applications. Both are also pin-for-pin compatible with the Z8F082A family.
