SAM3N Series
Atmel | SMART ARM-based MCU
DATASHEET Description
The Atmel В® | SMART SAM3N series is a member of a family of Flash
microcontrollers based on the high performance 32-bit ARMВ® CortexВ®-M3 RISC
processor. It operates at a maximum speed of 48 MHz and features up to
256 Kbytes of Flash and up to 24 Kbytes of SRAM. The peripheral set includes 2
USARTs, 2 UARTs, 2 TWIs, 3 SPIs, as well as a PWM timer, two 3-channel
general-purpose 16-bit timers, an RTC, a 10-bit ADC, and a 10-bit DAC.
The SAM3N devices have three software-selectable low-power modes: Sleep,
Wait and Backup. In Sleep mode, the processor is stopped while all other
functions can be kept running. In Wait mode, all clocks and functions are stopped
but some peripherals can be configured to wake up the system based on
predefined conditions. In Backup mode, only the RTC, RTT, 256-bit GPBR, and
wake-up logic are running.
The Real-time Event Managment allows peripherals to receive, react to and send
events in Active and Sleep modes without processor intervention.
The SAM3N series is ready for capacitive touch thanks to the Atmel QTouchВ®
library, offering an easy way to implement buttons, wheels and sliders.
The SAM3N device is an entry-level general purpose microcontroller. That makes
