Are you looking for a microcontroller (MCU) with blazing-fast speed, large memory, high-performance motor control peripherals and advanced communication? The SAM E7x/S7x series has it all. Building on the performance of the Arm® Cortex®-M4F based SAM D5x/E5x series, the SAM E7x/S7x series features a 300 MHz Arm Cortex-M7 core with up to 128 KB of tightly coupled memory and double-precision floating-point math processing.
The SAM E7x/S7x series of MCUs features highly advanced analog and Pulse-Width Modulation (PWM) peripherals to enable high-performance, dual-motor control with a single MCU. Each of the integrated 2 Msps dual-sample-and-hold Analog-to-Digital Converters (ADCs) has built-in programmable gain amplifiers. In a dual motor setup, each pair of feedback resistors would feed its own ADC module to implement sensorless motor control.

MPLAB® Harmony, a flexible, abstracted, fully integrated firmware development platform for PIC32 and SAM MCUs, provides support for peripherals, application demos and motor control applications using the SAM D5x/E5x family of MCUs. It provides easy-to-use software modules targeted for motor control that work together in complete harmony and can be configured to meet your specific requirements. It also includes a set of peripheral libraries, drivers and system services that are easily accessible for your application development. The code development format allows for maximum re-use and reduces your time to market.
We offer the following motor control development boards to simplify your development with SAM D5x/E5x devices. You will also need to purchase the ATSAME54 Motor Control Plug-In Module to add a SAM D5x/E5x device to your design. Demo examples for sensored and sensorless Field Oriented Control (FOC) of a permanent magnet synchronous motor are available within MPLAB Harmony v3.
