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 frequencies 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 90ОјA/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 (<1.5Ојs) and a very
low consumption of, respectively, 3 ОјA and 1.5 ОјA. In addition, WAIT mode supports SleepWalking features. In BACKUP mode, CPU, peripherals and RAM are
powered off and, while consuming less than 0.9ОјA with external interrupt wakeup supported.
The SAM4L series offers a wide range of peripherals such as segment LCD controller, embedded hardware capacitive touch (QTouch), USB device &
embedded host, 128-bit AES and audio interfaces in addition to high speed
serial peripherals 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. ATSAM-e
