Naming rule for
H8/300H mask ROM
parts
HD643 + device body+ revision +
code/speed + ROM code + package
+ temperature
device body 4-digit code of desired
H8/300H derivative,e.g.
3042 for H8/3042
revision S for mask revision or
omitted,for new
inquiries always use ‘S’
(where applicable)
ROM code 2-digit number assigned
to mask after customer
code submission
code/speed A. . E 16MHz/5V
F.. H 12MHz/5V
K,L 10MHz/5V
M 18MHz/5V
P 17MHz/5V
S 13MHz/3.15
...5.5V
T,U 10MHz/3.0
(or 3.15V)

When the “ROM code”overflows
(>99) the “code/speed” digit advances,e.
g. from A99 to B00.

Example:HD6433032SMxxF is a mask
ROM H8/3032S (mask revision),with
18MHz/5V in FP-80A package (14mm

Example:HD6432357AxxFI is a mask
ROM H8S/2357, with 20MHz/5V in
FP-128 package (20mm x 14mm) in I-
spec. xx will be determined after ROM
code submission.
Pseudo ROM-less derivatives
These devices are mask ROM H8/300H
or H8S with a blank ROM,for which
standard ROM-less commercial criteria
apply (e. g. minimum order quantity).
The part names comply with the
masked ROM naming rule (please see
above).
Microcontrollers for wide
temperature range (WTR)
All of Hitachi’s microcontrollers are
available in several temperature ranges.
The standard temperature range is
-20°C. . 75°C and is not indicated in the
package suffix.
-40°C. . 85°C (I and J-spec)
Hitachi offers two specifications for -
40°C. . 85°C. These are indicated in the
package suffix by I and J. I-spec has a
wider temperature range compared with
standard spec, but has the same reliability.
J-spec has improved reliability compared
with standard spec. Hitachi recommends
to use J-spec for critical applications,
particularly in industrial and automotive
applications.
-40°C. . 105°C (JE-spec)
JE-spec has the same reliability as J-spec
but extends the operating temperature
range to 105°C. This should - for
example - be used in critical applications
for automotive safety.
-40°C. . 125°C (K-spec)
K-spec further extends the temperature
range to 125°C and also improves
reliability over JE-spec. We recommend
this for important safety features in the
automotive market,where the product is
installed e. g. near the engine.
If you require JE- or K-spec, please
contact your Hitachi sales office or
authorized distributor.
