To all our customers
Regarding the change of names mentioned in the document, such as Hitachi
Electric and Hitachi XX, to Renesas Technology Corp.
The semiconductor operations of Mitsubishi Electric and Hitachi were transferred to Renesas
Technology Corporation on April 1st 2003. These operations include microcomputer, logic, analog
and discrete devices, and memory chips other than DRAMs (flash memory, SRAMs etc.)
Accordingly, although Hitachi, Hitachi, Ltd., Hitachi Semiconductors, and other Hitachi brand
names are mentioned in the document, these names have in fact all been changed to Renesas
Technology Corp. Thank you for your understanding. Except for our corporate trademark, logo and
corporate statement, no changes whatsoever have been made to the contents of the document, and
these changes do not constitute any alteration to the contents of the document itself.

Cautions
Keep safety first in your circuit designs!
1.
Renesas Technology Corporation puts the maximum effort into making semiconductor products better and more reliable, but
there is always the possibility that trouble may occur with them. Trouble with semiconductors may lead to personal injury, fire
or property damage.
Remember to give due consideration to safety when making your circuit designs, with appropriate measures such as (i)
placement of substitutive, auxiliary circuits, (ii) use of nonflammable material or (iii) prevention against any malfunction or
mishap.

Preface
The H8/300L Series of single-chip microcomputers has the high-speed H8/300L CPU at its core,
with many necessary peripheral functions on-chip. The H8/300L CPU instruction set is
compatible with the H8/300 CPU.
The H8/38024 Series has a system-on-a-chip architecture that includes such peripheral functions
as an LCD controller/driver, six timers, a two-channel 10-bit PWM, a serial communication
interface, and an A/D converter. This allows H8/38024 Series devices to be used as embedded
microcomputers in systems requiring LCD display.
Its on-chip ROM is PROM (ZTAT“), single-
power-supply flash memory (F-ZTAT“), and mask ROM that provides flexibility as it can be
reprogrammed in no time to cope with all situations from the early stages of mass production to
full-scale mass production. This is particularly applicable to application devices with
specifications that will most probably change.
This manual describes the hardware of the H8/38024 Series. For details on the H8/38024 Series
instruction set, refer to the H8/300L Series Programming Manual.
Notes:
Please follow the limitations below when developing a program and debugging H8/38024 using
the on-chip emulator (E10T).
1. The P95 pin is not available for use because it is dedicated to E10T.
2. The P33, P34, and P35 pins are also not available for use. To use these pins, additional
hardware is required on the user’s board.
3. Users cannot use the regions of addresses H'7000 to H'7FFF because they are used by E10T.
4. Regions of addresses H'F780 to H'FB7F must not be accessed.
5. When E10T is used, the P95 pin is for I/O, the P33 and P34 pins are for input, and the P35 pins
is for output.
