ATSAM3N4CA-AU概述

ATMEL  ATSAM3N4CA-AU  微控制器, 32位, SAM3N系列, ARM 皮质-M3, 48 MHz, 256 KB, 24 KB, 100 引脚, QFP

The is a SMART SAM3N2A series 32-bit Flash Microcontroller based on the high-performance ARM Cortex-M3 RISC processor. It operates at a maximum speed of 48MHz and features 256kB of flash memory and 24kB of SRAM. The peripheral set includes an 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 SAM3N4C is ready for capacitive touch thanks to the Atmel QTouch® library, offering an easy way to implement buttons, wheels and sliders. It operates from 1.62 to 3.6V. The SAM3N4C is pin-to-pin compatible with the SAM3S4C. It is ready for capacitive touch with QTouch library, offering an easy way to implement buttons, wheels and sliders. The real-time event management allows peripherals to receive, react to and send events in active and sleep modes without processor intervention.
