Hot-selling and scarce ATSAM3N00BA-AU Microcontroller IC 32-Bit 48MHz 16KB 64-LQFP spot stock

Product Descriptions

The SAM3N devices have three software-selectable low-power modes: Sleep,Wait and Backup . In Sleep mode, the processor is stopped while all otherfunctions can be kept running . In Wait mode, all clocks and functions are stoppedbut some peripherals can be configured to wake up the system based onpredefined conditions . In Backup mode, only the RTC, RTT, 256-bit GPBR, andwake-up logic are running .

The Real-time Event Managment allows peripherals to receive, react to and sendevents in Active and Sleep modes without processor intervention .
