Average power supply current lOOp istypically 15 mA at 2% duty cycle.Note 4: Maximum duty cycle of t¢pw should not be greater than 2% of cycle time so that powerdissipation is minimized. To guarantee long term memory retention the program cycle should be reopeated five times with t¢pw ~ 20 ms or the equivalent thereof, i.e. 10 cycles of t¢pw ~ 10 ms.68
