Preface
The H8/3048 Series is a series of high-performance microcontrollers 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 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, a D/A converter, I/O ports, a direct memory access controller
(DMAC), a refresh controller, and other facilities. Of the two SCI channels, one has been
expanded to support the ISO/IEC7816-3 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 address space is divided into eight areas. The data bus width and access cycle length can be
selected independently in each area, simplifying the connection of different types of memory.
Seven operating modes (modes 1 to 7) are provided, offering a choice of data bus width and
address space size.
With these features, the H8/3048 Series can be used to implement compact, high-performance
systems easily.
In addition to its masked-ROM versions, the H8/3048 Series has a ZTAT™*
1
version with user-
programmable on-chip PROM and an F-ZTAT™*
2
version with 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 H8/3048 Series hardware. For details of the instruction set, refer to the
H8/300H Series Programming Manual.
