Preface
The H8/3337 Series and H8/3397 Series are series of high-performance microcontrollers with a fast
H8/300 CPU core and a set of on-chip supporting functions optimized for embedded control. These
include ROM, RAM, four types of timers, a serial communication interface, I
2
C bus interface, host
interface, A/D converter, D/A converter, I/O ports, and other functions needed in control system
configurations, so that compact, high-performance systems can be implemented easily. The
H8/3397 Series is a subset of the H8/3337 Series and does not include a host interface and D/A
converter. H8/3337 Series includes the H8/3337Y with 60-kbyte ROM and 2-kbyte RAM, the
H8/3336Y with 48-kbyte ROM and 2-kbyte RAM, and the H8/3334Y with 32-kbyte ROM and
1-kbyte RAM. H8/3397 Series includes the H8/3397 with 60-kbyte ROM and 2-kbyte RAM, the
H8/3396 with 48-kbyte ROM and 2-kbyte RAM, and the H8/3394 with 32-kbyte ROM and 1-kbyte
RAM.
The H8/3337Y, and H8/3334Y are available in mask-ROM versions and in ZTAT™
*1
(zero turn-
around time) versions, providing a quick and flexible response to conditions from ramp-up through
full-scale volume production, even for applications with frequently-changing specifications. In
addition, the H8/3334Y and H8/3337Y have an F-ZTAT™
*2
(flexible-ZTAT) version with on-
board programmability.
This manual describes the hardware of the H8/3337 Series and H8/3397 Series. Refer to the
H8/300
Series Programming Manual
for a detailed description of the instruction set.
