Preface

The H8/3048 Group 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 Group can be used to implement compact, high-performance

systems easily.

In addition to its mask ROM versions, the H8/3048 Group 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.

The on-chip emulator (E10T) is installed on the H8/3048F-ONE in the H8/3048 Group

microcomputer. Refer to the H8/3048F-ONE Hardware Manual for details.

This manual describes the H8/3048 Group hardware. For details of the instruction set, refer to the

H8/300H Series Programming Manual.
