ATMEL  ATSAM4N16BA-AU  微控制器, 32位, SAM4N系列, ARM 皮质-M4, 100 MHz, 1 MB, 80 KB, 64 引脚, QFP

The is a SMART SAM4N series 32-bit Flash Microcontroller based on the high-performance ARM Cortex-M4 RISC processor. It operates at a maximum speed of 100MHz and features 1MB of flash memory and 80kB of SRAM. Peripherals include six USARTs, three SPIs and three I²Cs for fast serial communication, as well as a 10-channel 12-bit ADC, a 10-bit DAC, PWM, timers and RTC. The device operates from 1.62 to 3.6 V. It is a medium range general purpose microcontroller with the best ratio in terms of reduced power consumption, processing power and peripheral set.
