Notes 1. Make sure that the following conditions of the VPP voltage application timing are satisfied when the flash
memory is written.
• When supply voltage rises
V
PP must exceed VDD 10 µ s or more after VDD has reached the lower-limit value (1.8 V) of the operating
voltage range (see a in the figure below).
• When supply voltage drops
VDD must be lowered 10 µ s or more after VPP falls below the lower-limit value (1.8 V) of the operating
voltage range of V
DD (see b in the figure below).
