Notes on differences among 3850 group
(standard), 3850 group (spec. H), and 3850
group (spec. A)
(1) The absolute maximum ratings of 3850 group (spec. H/A) is
smaller than that of 3850 group (standard).
Power source voltage Vcc =
0.3 to 6.5 V
CNVss input voltage V
I
=
0.3 to Vcc +0.3 V
(2) The oscillation circuit constants of X
IN
-X
OUT
, X
CIN
-X
COUT
may
be some differences among 3850 group (standard), 3850
group (spec. H), and 3850 group (spec. A).
(3) Do not write any data to the reserved area and the reserved
bit. (Do not change the contents after reset.)
(4) Fix bit 3 of the CPU mode register to
1
.
(5) Be sure to perform the termination of unused pins.
