ARM-based Flash MCU

Atmel Corporation 

1. SAM3N Description

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.
