SAM 4L MCUs
Redefining Low Power in ARM® Cortex® M4 based Microcontrollers
SAM4L microcontrollers (MCUs) redefine the power benchmark for Cortex®-M4 processor-based devices, delivering the lowest power in active mode (down to 90µA/MHz) as well as sleep mode with full RAM retention (1.5µA) with the shortest wake-up time (down to 1.5µs). Embedding Microchip picoPower® technology, the SAM4L family provides highly efficient signal processing, ease of use and high-speed communication peripherals—ideal for power-sensitive designs in the industrial, healthcare and consumer application areas.

Key Features
- Microchip picoPower Technology — Ensures that devices are developed from the ground up for the lowest power consumption possible, enabling long battery life
- Microchip QTouch® Capacitive Touch Support — Includes hardware integrated capacitive touch module based on QTouch® technology for fast development of touch and proximity functionality with ultra low power consumption
- Highly Efficient Signal Processing — Thanks to the Cortex-M4 architecture, the SAM4L microcontrollers feature extended single-cycle multiply-accumulate instructions, optimized SIMD arithmetic and saturating arithmetic instructions for highly efficient signal processing
- Ease of Use — Its ecosystem of software tools and support for Microchip Studio 6 integrated development environment enables an efficient design process and reduces time to market
