SAM4L Series Microcontrollers

SAM4L Series Microcontrollers

Microchip’s SAM4L series of microcontrollers (MCUs) redefine the power benchmark for Cortex-M4 processor-based devices, delivering the lowest power in active mode (down to 90 µA/MHz), as well as sleep mode with full RAM retention (1.5 µA) with the shortest wake-up time (down to 1.5 µs). 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 consumer, industrial, healthcare, and IoT application areas.

These products are compatible with Microchip advance software framework which includes Atmel Studio and Atmel START.  This software framework provides a large collection of embedded software for Atmel® Flash microcontrollers including megaAVR®, AVR XMEGA®, AVR UC3 and SAM devices which simplifies the usage of microcontrollers, providing an abstraction to the hardware and high-value middleware. The Microchip 32-bit software framework also includes a graphical user interface or can be a standalone for GCC or IAR compilers.
