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 H8/3834U Series has a system-on-a-chip architecture that includes such peripheral functions
as an LCD controller/driver, five types of timers, a 14-bit PWM, a three-channel serial
communication interface, and an A/D converter. This makes it ideal for use in systems requiring
an LCD display.
This manual describes the hardware of the H8/3834U Series. For details on the H8/3834U Series
instruction set, refer to the H8/300L Series Programming Manual.
