Preface
The H8/3847 Group 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 Renesas Technology Corp.
Intended Readership: This manual is intended for users undertaking the design of an application
system using the H8/3847 Group. Readers using this manual require a basic
knowledge of electrical circuits, logic circuits, and microcomputers.
