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.

Preface
The H8/3847 Series is a high-performance single-chip microcomputer that integrates peripheral
functions necessary for system configuration with an H8/300L CPU core.
The on-chip peripheral functions include ROM, RAM, six timers, 14-bit PWM, a serial
communication interface (SCI), an A/D converter, LCD controller/driver, and I/O ports, providing
an ideal configuration as a microcomputer for embedding in sophisticated control systems.
PROM(Z-TAT™*) and mask ROM are available as on-chip ROM, enabling users to respond
quickly and flexibly to changing application specifications and the demands of the transition from
initial to full-fledged volume production.
Note: * F-ZTAT is a trademark of Hitachi, Ltd.
