Notes 2.
Make sure that the following conditions of the V
PP
voltage application timing are satisfied when the flash
memory is written.
When supply voltage rises
V
PP
must exceed V
DD
10
μ
s or more after V
DD
has reached the lower-limit value (1.8 V) of the
operating voltage range (see a in the figure below).
When supply voltage drops
V
DD
must be lowered 10
μ
s or more after V
PP
falls below the lower-limit value (1.8 V) of the
operating voltage range of V
DD
(see b in the figure below).
