Summary Atmel's SAM4L series is a member o f a family of Flash microcontrollers based on the high performance 32-bit ARM Cortex-M4 RISC processor running at fre- quencies up to 48MHz. The SAM4L series embeds state-of-the-art picoPower technology for ultra-low power consumption. Combined power control techniques are used to bring active current consumption down to 90µA/MHz. The device allows a wide range of options be tween functionalit y and po wer consumpt ion, giving the u ser th e ability to rea ch the l owest poss ible power consumpt ion wi th t he feature set required for the application. The WAIT and RETENTION modes provide full logic and RAM retention, associated with fast wake-up capability (<1.5µs) and a very low consumption of, respectively, 3 µA and 1.5 µA. In addition, WAIT mode sup- ports SleepWalking features. In BACKUP mode, CPU, peripherals and RAM are powered off and, while consuming less than 0.9µA with external interrupt wake- up supported. The SAM4L series offers a wide range of peripherals such as segment LCD con- troller, embedded hardware capacitive touch (QTouch), USB device & embedded host, 128-bit AES and audio interfaces in addition to high speed serial peripher- als such as USART, SPI and I 2C. Additionally the Peripheral Event System and SleepWalking allo ws the peripherals to comm unicate direc tly with each other and make intelligent decisions and decide to wake-up the system on a qualified events on a peripheral level; such as I2C address match or and ADC threshold.
