产品概述
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 64KB of flash and 8KB of SRAM. The peripheral set includes an USART, two UARTs, two SPIs, two TWIs, PWM timer, six 16-bit timers, RTC and a 10-bit ADC. The SAM3N1B 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 64-pin LQFP and QFN packages. The SAM3N1B is pin-to-pin compatible with the SAM3S1B and SAM7S64.
