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 90 A/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
ATSAM---e
required for the application. The WAIT and RETENTION modes provide full logic
and RAM retention, associated with fast wake-up capability (<1.5s) and a very
ARM-based
low consumption of, respectively, 3 A and 1.5 A. In addition, WAIT mode sup-
Flash MCU
ports SleepWalking features. In BACKUP mode, CPU, peripherals and RAM are
powered off and, while consuming less than 0.9 A with external interrupt wake-
up supported.
SAM4L Series
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
2
serial peripherals such as USART, SPI and I C. 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
2
a qualified events on a peripheral level; such as I C address match or and ADC
threshold.
