Cautions
1. Hitachi neither warrants nor grants licenses of any rights of Hitachi’s or any third party’s
patent, copyright, trademark, or other intellectual property rights for information contained in
this document. Hitachi bears no responsibility for problems that may arise with third party’s
rights, including intellectual property rights, in connection with use of the information
contained in this document.
2. Products and product specifications may be subject to change without notice. Confirm that you
have received the latest product standards or specifications before final design, purchase or
use.
3. Hitachi makes every attempt to ensure that its products are of high quality and reliability.
However, contact Hitachi’s sales office before using the product in an application that
demands especially high quality and reliability or where its failure or malfunction may directly
threaten human life or cause risk of bodily injury, such as aerospace, aeronautics, nuclear
power, combustion control, transportation, traffic, safety equipment or medical equipment for
life support.
4. Design your application so that the product is used within the ranges guaranteed by Hitachi
particularly for maximum rating, operating supply voltage range, heat radiation characteristics,
installation conditions and other characteristics. Hitachi bears no responsibility for failure or
damage when used beyond the guaranteed ranges. Even within the guaranteed ranges,
consider normally foreseeable failure rates or failure modes in semiconductor devices and
employ systemic measures such as fail-safes, so that the equipment incorporating Hitachi
product does not cause bodily injury, fire or other consequential damage due to operation of
the Hitachi product.
5. This product is not designed to be radiation resistant.
6. No one is permitted to reproduce or duplicate, in any form, the whole or part of this document
without written approval from Hitachi.
7. Contact Hitachi’s sales office for any questions regarding this document or Hitachi
semiconductor products.
General Precautions on Handling of Product
1. Treatment of NC Pins
Note: Do not connect anything to the NC pins.
The NC (not connected) pins are either not connected to any of the internal circuitry or are
they are used as test pins or to reduce noise. If something is connected to the NC pins, the
operation of the LSI is not guaranteed.
2. Treatment of Unused Input Pins
Note: Fix all unused input pins to high or low level.
Generally, the input pins of CMOS products are high-impedance input pins. If unused pins
are in their open states, intermediate levels are induced by noise in the vicinity, a pass-
through current flows internally, and a malfunction may occur.
3. Processing before Initialization
Note: When power is first supplied, the product’s state is undefined.
The states of internal circuits are undefined until full power is supplied throughout the
chip and a low level is input on the reset pin. During the period where the states are
undefined, the register settings and the output state of each pin are also undefined. Design
your system so that it does not malfunction because of processing while it is in this
undefined state. For those products which have a reset function, reset the LSI immediately
after the power supply has been turned on.
4. Prohibition of Access to Undefined or Reserved Addresses
Note: Access to undefined or reserved addresses is prohibited.
The undefined or reserved addresses may be used to expand functions, or test registers
may have been be allocated to these addresses. Do not access these registers; the system’s
operation is not guaranteed if they are accessed.
Preface
The SH7046 Series single-chip RISC (Reduced Instruction Set Computer) microprocessor
includes a Hitachi-original RISC CPU as its core, and the peripheral functions required to
configure a system.
Target users: This manual was written for users who will be using the SH7046 Series Micro-
Computer Unit(MCU) in the design of application systems. Users of this manual 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 the SH7046 Series MCU to the above users.
Refer to the SH-1, SH-2, SH-DSP Programming Manual for a detailed description
of the instruction set.

Product Code
HD64F7046
HD6437148
HD64F7047
HD6437049
In this manual, the product abbreviations are used to distinguish products. For example, 80-pin
products are collectively referred to as the SH7046, an abbreviation of the basic type's
classification code, while 100-pin products are collectively referred to as the SH7047. There
are two versions of each: a flash memory version and a mask ROM version. When a
description is limited to the flash memory version alone, the character F is added at the end of
the abbreviation, such as SH7046F. When a description is limited to the mask ROM version
alone, an abbreviation that is determined by the ROM size is used; SH7148 is used to indicate
the 80-pin mask ROM version.

The typical product
The HD64F7046 is taken as the typical product for the descriptions in this manual.
Accordingly, when using an HD6437148, HD64F7047, or HD6437049, simply replace the
HD64F7046 in those references where no differences between products are pointed out with
HD6437148, HD64F7047, or HD6437049. Where differences are indicated, be aware that each
specification apply to the products as indicated.
•
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.
•
In order to understand the details of the CPU's functions
Read the SH-1, SH-2, SH-DSP Programming Manual.
•
In order to understand the details of a register when the user knows its name
Read the index that is the final part of the manual to find the page number of the entry on the
register. The addresses, bit names, and initial values of the registers are summarized in
Appendix A, On-chip I/O Register.
Rules:
Register name:
The following notation is used for cases when the same or a
similar function, e.g. serial communication, is implemented
on more than one channel:
XXX_N (XXX is the register name and N is the channel
number)
The MSB (most significant bit) is on the left and the LSB
(least significant bit) is on the right.
Bit order:
