SAM4L Datasheet, PDF (1110/1185 Pages) ATMEL Corporation – ATSAM ARM-based Flash MCU

ATSAM4L4/L2
• Wake up time from low power modes is measured from the edge of the wakeup signal to the
first instruction fetched in flash.
• Oscillators
– OSC0 (crystal oscillator) stopped
– OSC32K (32kHz crystal oscillator) running with external 32kHz crystal
– DFLL using OSC32K as reference and running at 48MHz
• Clocks
– DFLL used as main clock source
– CPU, AHB clocks undivided
– APBC and APBD clocks divided by 4
– APBA and APBB bridges off
– The following peripheral clocks running
• PM, SCIF, AST, FLASHCALW, APBC and APBD bridges
– All other peripheral clocks stopped
• I/Os are inactive with internal pull-up
• CPU is running on flash with 1 wait state
• Low power cache enabled
• BOD18 and BOD33 disabled
