picoPower
®
technology, the Atmel SAM4L
family redefines the power benchmark, delivering the
industry’s most efficient MCU:
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:
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
