Keep safety first in your circuit designs!
1. Renesas Technology Corp. puts the maximum effort into making semiconductor products better and
more reliable, but there is always the possibility that trouble may occur with them. Trouble with
semiconductors may lead to personal injury, fire or property damage.
Remember to give due consideration to safety when making your circuit designs, with appropriate
measures such as (i) placement of substitutive, auxiliary circuits, (ii) use of nonflammable material or
(iii) prevention against any malfunction or mishap.
Notes regarding these materials
1. These materials are intended as a reference to assist our customers in the selection of the Renesas
Technology Corp. product best suited to the customer's application; they do not convey any license

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 SH7058 is a single-chip RISC (reduced instruction set computer) microcomputer that has the
32-bit internal architecture CPU, SH-2E, as its core, and also includes peripheral functions
necessary for system configuration.
The SH7058 is equipped with on-chip peripheral functions necessary for system configuration,
including a floating-point unit (FPU), large-capacity ROM and RAM, a direct memory access
controller (DMAC), timers, a serial communication interface (SCI), controller area network
(HCAN), A/D converter, and I/O ports, therefore, it can be used as a microprocessor built in a
high-level control system.
The SH7058 is an F-ZTAT™* (Flexible Zero Turn-Around Time) version with flash memory as
its on-chip ROM, and it can rapidly and flexibly deal with each situation on an application system
with fluid specifications from an early stage of mass production to full-scale production.
Note: * F-ZTAT™ is a trademark of Renesas Technology, Corp.
Target users: This manual was written for users who will be using the SH7058 F-ZTAT in the
design of application systems. Users of this manual are expected to understand
the fundamentals of electrical curcuits, logical circuits, and microcomputers.
Objective:
This manual was written to explain the hardware functions and electrical
characteristics of the SH7058 F-ZTAT to the above users.
Refer to the SH-2E 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.
•
In order to understand the details of the CPU's functions
Read the SH-2E Programming Manual.
Rule:
Bit order:
The MSB (most significant bit) is on the left and the LSB (least
significant bit) is on the right.
Releated Manuals: The latest versions of all related manuals are available from our web site.
Please ensure you have the latest versions of all documents you require.
