Preface
The H8/3039 Series comprises high-performance single-chip microcomputers (MCUs) that
integrate system supporting functions together with an H8/300H CPU core.
The H8/300H CPU has a 32-bit internal architecture with sixteen 16-bit general registers, and a
concise, optimized instruction set designed for speed. It can address a 16-Mbyte linear address
space.
The on-chip system supporting functions include ROM, RAM, a 16-bit integrated timer unit
(ITU), a programmable timing pattern controller (TPC), a watchdog timer (WDT), a serial
communication interface (SCI), an A/D converter, I/O ports, and other facilities. Of the two SCI
channels, one has been expanded to support the ISO/IEC 7816-3 smart card interface. Functions
have also been added to reduce power consumption in battery-powered applications: individual
modules can be placed in standby, and the frequency of the system clock supplied to the chip can
be divided down under software control.
The five MCU operating modes offer a choice of expanded mode, single-chip mode, and address
space size, enabling the H8/3039 Series to adapt quickly and flexibly to a variety of conditions.
TM
In addition to its masked-ROM versions, the H8/3039 Series has an F-ZTAT
* version with user
programmable on-chip flash memory that can be programmed on-board. These versions enable
users to respond quickly and flexibly to changing application specifications.
This manual describes the H8/3039 Series hardware. For details of the instruction set, refer to the
H8/300H Series Programming Manual.
