SAM4N8 / SAM4N16
Atmel | SMART ARM-based MCU
DATASHEET Description
The Atmel В® | SMART SAM4N series is a member of a family of Flash
microcontrollers based on the high performance 32-bit ARMВ® CortexВ®-M4 RISC
processor. It operates at a maximum speed of 100 MHz and features up to 1024
Kbytes of Flash and up to 80 Kbytes of SRAM. The peripheral set includes 3
USARTs, 4 UARTs, 3 TWIs, 1 SPI, as well as 1 PWM timer, 2 three-channel
general-purpose 16-bit timers (with stepper motor and quadrature decoder logic
support), a low-power RTC, a low-power RTT, 256-bit general purpose backup
registers, a 10-bit ADC (up to 12-bit with digital averaging) and a 10-bit DAC with
an internal voltage reference.
The SAM4N 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, 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 SAM4N device is a medium range general purpose microcontroller with the
best ratio in terms of reduced power consumption, processing power and
peripheral set. This enables the SAM4N to sustain a wide range of applications …
