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
VPP must exceed VDD 10
µ
s or more after VDD has reached the lower-limit value (4.0 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 (4.0 V) of the operating
voltage range of VDD (see b in the figure below).

Caution Product quality may suffer if the absolute maximum rating is exceeded even momentarily for
any parameter. That is, the absolute maximum ratings are rated values at which the product is
on the verge of suffering physical damage, and therefore the product must be used under
conditions that ensure that the absolute maximum ratings are not exceeded.
Remark Unless specified otherwise, the characteristics of alternate-function pins are the same as those of port
pins.
