This allows the peripherals to qualify an event and decide to wake-up whether it is from capacitive touch, I2C address match or an ADC threshold. In addition, SleepWalking technology allows a peripheral to qualify and evaluate incoming data without the use of the CPU, eliminating unneeded, power-consuming CPU wake-ups to conserve power. The Peripheral Event System is a real-time network that allows peripherals to communicate directly with one another without using the central processing unit (CPU).

The devices take advantage of the numerous Atmel picoPower power-saving innovations, including SleepWalking, Peripheral Event System, unrivaled wake-up times and intelligent peripherals. With wake-up times down to 1.5µs from the deepest sleep modes, the SAM4L family has been designed for battery-powered consumer, industrial and portable healthcare products. In sleep mode, the devices consume 1.5♚ with full random access memory (RAM) retention, and 700nA in back-up mode.

The SAM4L family consumes down to 90♚/MHz in active mode and is able to achieve up to 28 CoreMark/mA using the IAR Embedded Workbench, version 6.40. The SAM4L family is the industry”s first device to provide ultra-low power consumption bundled with wake-up times while delivering total application performance in all operating modes. Incorporating the company”s proprietary ultra-low power picoPower technology, the SAM4L family consumes just one-third the power of current solutions.

The Atmel Corporation claims to have set new low-power and efficiency standards for ARM Cortex-M4 processor-based microcontrollers (MCUs) with the launch of the new SAM4L family of devices.
