Renesas Electronics 

Preface

The H8S/2678 Group and H8S/2678R Group are microcomputers (MCU) made up of the

H8S/2600 CPU employing Renesas’ original architecture as their cores, and the peripheral

functions required to configure a system.

The H8S/2600 CPU has an internal 32-bit configuration, sixteen 16-bit general registers, and a

simple and optimized instruction set for high-speed operation. The H8S/2600 CPU can handle a

16-Mbyte linear address space.

This LSI is equipped with direct memory access controller (DMAC and EXDMAC) and data

transfer controller (DTC) bus masters, ROM and RAM, a 16-bit timer pulse unit (TPU), a

programmable pulse generator (PPG), an 8-bit timer (TMR), a watchdog timer (WDT), a serial

communication interface (SCI and IrDA), a 10-bit A/D converter, an 8-bit D/A converter, and I/O

ports as on-chip peripheral modules required for system configuration

A high functionality bus controller is also provided, enabling fast and easy connection of DRAM,

SDRAM, and other kinds of memory.

A single-power flash memory (F-ZTAT*) version and masked ROM version are available for

this LSI's ROM. The F-ZTAT version provides flexibility as it can be reprogrammed in no time to

cope with all situations from the early stages of mass production to full-scale mass production.

This is particularly applicable to application devices with specifications that will most probably

change.

This manual describes this LSI’s hardware.

Note: * F-ZTAT is a trademark of Renesas Technology Corp.

Target Users: This manual was written for users who will be using this LSI in the design of

application systems. Target users are expected to understand the fundamentals of

electrical circuits, logical circuits, and microcomputers.

Objective:

This manual was written to explain the hardware functions and electrical

characteristics of this LSI to the target users.

Refer to the H8S/2600 Series, H8S/2000 Series Programming Manual for a

detailed description of the instruction set.

Notes on reading this manual:

In order to understand the overall functions of the chip

Read the manual according to the contents. This manual can be roughly categorized into parts

on the CPU, system control functions, peripheral functions and electrical characteristics.
