Microchip's SAM3N series is a member of a family of Flash microcontrollers based on the high performance 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 two USARTs, two UARTs, two TWIs, three SPI, as well as one PWM timer, six 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 1.62 V to 3.6 V and is available in 48-pin, 64-pin and 100-pin QFP, 48-pin and 64-pin QFN, and 100-pin BGA packages.
