SAM L Arm^® Cortex^®-M-Based Microcontrollers (MCUs)

A rich set of peripherals, flexibility and ease of use combined with lowest power consumption in its class, and an enhanced Peripheral Touch Controller (PTC) make the industry’s first Arm Cortex-M23 based microcontrollers ideal for IoT devices, wearables, appliances, low-power industrial applications, metering, battery-powered accessories and general-purpose embedded control. Offering identical peripheral modules, compatible code and a linear address map, the SAM L10 family is designed for simple and intuitive migration between SAM L devices. It is also compatible with the SAM D family of general-purpose MCUs.
