SAM3N2A

SAM3N Series Atmel | SMART ARM-based MCU DATASHEET Description The Atmel® | SMART 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 2 USARTs, 2 UARTs, 2 TWIs, 3 SPIs, as well as a PWM timer, two 3-channel general-purpose 16-bit timers, an RTC, a 10-bit ADC, and a 10-bit DAC. The SAM3N devices have three software-selectable low-power modes: Sleep, Wait and Backup. In Sleep mode, the processor is stopped while all other functions can be kept running. In Wait mode, all clocks and functions are stopped but some peripherals can be configured to wake up the system based on predefined conditions. In Backup mode, only the RTC, RTT, 256-bit GPBR, and wake-up logic are running. The Real-time Event Managment allows peripherals to receive, react to and send events in Active and S...
