1 / 176 page  Summary Atmel's SAM4L series is a member of 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 between functionality and power consumption, giving the user the ability to reach the lowest possible power consumption with the 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 I2C. Additionally the Peripheral Event System and SleepWalking allows the peripherals to communicate directly 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.
