Product Announcement from Atmel Corporation
The SAM4L family integrates Atmel's proprietary picoPower® technology which ensures that devices are developed from the ground up—from transistor design to clocking options—to consume as little power as possible. Fast wakeup and innovative power-saving features reduce the overall consumption even further. In addition, Atmel's SleepWalking technology allows the peripherals to make intelligent decisions and wake up the system upon qualifying events at the peripheral level. It's all about system intelligence and conserving energy. Simply put, the SAM4L MCU is your choice if you're looking for long battery life, without sacrificing performance.
