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.
