Preface
The H8/3217 Series is a family of high-performance single-chip microcomputers ideally suited for
embedded control of industrial equipment. The chips are built around an H8/300 CPU core: a high-speed
processor. On-chip supporting modules provide ROM, RAM, four types of timers, I/O ports, a serial
communication interface, I
2
C bus interface, and host interface for easy implementation of compact, high-
speed control systems.
The H8/3217 Series offers a selection of on-chip memory.
H8/3217:
H8/3216:
H8/3214:
H8/3212:
60-kbyte ROM;
48-kbyte ROM;
32-kbyte ROM;
16-kbyte ROM;
2-kbyte RAM
2-kbyte RAM
1-kbyte RAM
512-byte RAM
The H8/3217 and H8/3214 chips are available with electrically programmable ROM. Manufacturers can use
the electrically programmable ZTAT™ (Zero Turn-Around Time*) version to get production off to a fast
start and make software changes quickly.
This manual describes the H8/3217 Series hardware. Refer to the
H8/300 Series Programming Manual
for a
detailed description of the instruction set.
