Key Applications
Designed from the ground up to be the industrys most
power-efficient Cortex-M4 processor-based MCUs,
the SAM4L family is ideal for battery-powered industrial,
medical and consumer devices. Examples include:
sensors and detectors, glucose and blood pressure
meters, remote controls and toys.

Ultra-low power consumption: picoPower technology ensures that devices are designed to consume the lowest
power possible, while delivering long battery life without any performance sacrifice.
Highly efficient signal processing: Thanks to the Cortex-M4 core, the SAM4L family provides highly efficient
signal processing with extended single-cycle multiply-accumulate instructions, optimized SIMD arithmetic and
saturating arithmetic instructions.
Intelligent and efficient peripherals: SAM4L devices offer a broad range of peripherals that are integrated into the
Peripheral Event System and feature SleepWalking technology, along with other embedded power-saving features.
Ease of use: Backed by an ecosystem of design tools, the SAM4L family is easy to use, facilitating faster time to market.
Design with the Atmel Studio integrated development environment (IDE), which includes thousands of project examples
with source code, simulation tools and a powerful editor.
