Preface
The H8/3437 Series is a high-performance single-chip microcomputer that integrates peripheral
functions necessary for system configuration with an H8/300 CPU featuring a 32-bit internal
architecture as its core.
On-chip peripheral functions include ROM, RAM, four kinds of timers, a serial communication
interface (SCI), host interface (HIF), keyboard controller, D/A converter, A/D converter, and I/O
ports, enabling the H8/3437 Series to be used as a microcontroller for embedding in high-speed

control systems. Flash memory (F-ZTAT™ ), PROM (ZTAT® ), 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.
