A member of the Atmel® 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 256KB of flash and 24KB of SRAM. The peripheral set includes an USART, two UART, two SPIs, two TWIs, PWM timer, six 16-bit timers, an RTC and a 10-bit ADC. The SAM3N4A is ready for capacitive touch thanks to the Atmel QTouch® library, offering an easy way to implement buttons, wheels and sliders. It operates from 1.62V to 3.6V and is available in 48-pin LQFP and QFN packages. The SAM3N4A is pin-to-pin compatible with the SAM3S4A.
