Flash
Atmel's SAM3N series is a member of a family of Flash microcontrollers based on the high per-
formance 32-bit ARM Cortex-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 2x USARTs, 2x UARTs, 2x TWIs, 3x SPI, as well as 1 PWM timer, 6x general purpose
16-bit timers, an RTC, a 10-bit ADC and a 10-bit DAC.
The SAM3N series is ready for capacitive touch thanks to the QTouch library, offering an easy
way to implement buttons, wheels and sliders.
The SAM3N device is an entry-level general purpose microcontroller. That makes the SAM3N
the ideal starting point to move from 8- /16-bit to 32-bit microcontrollers.
It operates from 1.62V to 3.6V and is available in 48-pin, 64-pin and 100-pin QFP, 48-pin and
64-pin QFN, and 100-pin BGA packages.
The SAM3N series is the ideal migration path from the SAM3S for applications that require a
reduced BOM cost. The SAM3N series is pin-to-pin compatible with the SAM3S series. Its
aggressive price point and high level of integration pushes its scope of use far into cost-sensi-
tive, high-volume applications.
The SAM3N4/2/1 differ in memory size, package and features list.
