Atmel SAM4L-EK Atmel ATSAM4L-EK ATSAM4L-EK Data Sheet

Atmel SAM4L Family  

Redefining the Power Benchmark:  
Lowest Active and Sleep Mode Power, 
Shortest Wake-Up Time

Based on the powerful ARM

®

 Cortex™-M4 processor and  

Atmel

®

 picoPower

®

 technology, the Atmel SAM4L  

family redefines the power benchmark, delivering the  
industry’s most efficient MCU:

•

Lowest power in active mode: 90µA/MHz

•

Lowest power in sleep mode: 1.5µA with full RAM retention 

•

Lowest power in backup mode: 700 nA

•

Shortest wake-up time: down to 1.5µs from deep-sleep mode

•

Up to 28 CoreMark/mA efficiency rating

•

Operating voltage: 1.68V-3.6V

Our patented picoPower technology provides innovative 
power-saving features:

•

SleepWalking intelligent peripherals—allows a peripheral 
to qualify and evaluate incoming data without  
using the CPU, eliminating unneeded processor wake-ups 
and conserving power

•

Peripheral Event System—a real-time network that  
allows peripherals to communicate directly with each 
other without using the CPU

•

Unrivaled wake-up—whether on a proximity, a touch,  
an I

2

C address match or an ADC threshold, all without 

using the CPU

Key Applications

Designed from the ground up to be the industry’s 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.
