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.
