Description

General part information

ATSAM3N00A Series

The Microchip's SAM3N1C is a member of the SAM3N series of microcontrollers based on the high-performance 32-bit ARM® Cortex®-M3 RISC processor.

It operates at a maximum speed of 48MHz and features 64KB of flash memory and 8KB of SRAM. The peripheral set includes a USART, two UARTs, two SPIs, two TWIs (I2C), PWM timer, six 16-bit timers, RTC, a 10-bit ADC, and a 10-bit DAC.

The SAM3N1C is ready for capacitive touch thanks to the Microchip QTouch library, offering an easy way to implement buttons, wheels, and sliders.
