particular application and specifically disclaims any liability arising out of the application and use of the
information in this document or Renesas products.
7. With the exception of products specified by Renesas as suitable for automobile applications, Renesas
products are not designed, manufactured or tested for applications or otherwise in systems the failure or
malfunction of which may cause a direct threat to human life or create a risk of human injury or which require
especially high quality and reliability such as safety systems, or equipment or systems for transportation and
traffic, healthcare, combustion control, aerospace and aeronautics, nuclear power, or undersea communication
transmission. If you are considering the use of our products for such purposes, please contact a Renesas
sales office beforehand. Renesas shall have no liability for damages arising out of the uses set forth above.
8. Notwithstanding the preceding paragraph, you should not use Renesas products for the purposes listed below:
(1) artificial life support devices or systems
(2) surgical implantations
(3) healthcare intervention (e.g., excision, administration of medication, etc.)
(4) any other purposes that pose a direct threat to human life
Renesas shall have no liability for damages arising out of the uses set forth in the above and purchasers who
elect to use Renesas products in any of the foregoing applications shall indemnify and hold harmless Renesas
Technology Corp., its affiliated companies and their officers, directors, and employees against any and all
damages arising out of such applications.
9. You should use the products described herein within the range specified by Renesas, especially with respect
to the maximum rating, operating supply voltage range, movement power voltage range, heat radiation
characteristics, installation and other product characteristics. Renesas shall have no liability for malfunctions or
damages arising out of the use of Renesas products beyond such specified ranges.
10. Although Renesas endeavors to improve the quality and reliability of its products, IC products have specific
characteristics such as the occurrence of failure at a certain rate and malfunctions under certain use
conditions. Please be sure to implement safety measures to guard against the possibility of physical injury, and
injury or damage caused by fire in the event of the failure of a Renesas product, such as safety design for
hardware and software including but not limited to redundancy, fire control and malfunction prevention,
appropriate treatment for aging degradation or any other applicable measures. Among others, since the
evaluation of microcomputer software alone is very difficult, please evaluate the safety of the final products or
system manufactured by you.
11. In case Renesas products listed in this document are detached from the products to which the Renesas
products are attached or affixed, the risk of accident such as swallowing by infants and small children is very
high. You should implement safety measures so that Renesas products may not be easily detached from your
products. Renesas shall have no liability for damages arising out of such detachment.
12. This document may not be reproduced or duplicated, in any form, in whole or in part, without prior written
approval from Renesas.
13. Please contact a Renesas sales office if you have any questions regarding the information contained in this
document, Renesas semiconductor products, or if you have any other inquiries.

General Precautions in the Handling of MPU/MCU Products
The following usage notes are applicable to all MPU/MCU products from Renesas. For detailed usage notes
on the products covered by this manual, refer to the relevant sections of the manual. If the descriptions under
General Precautions in the Handling of MPU/MCU Products and in the body of the manual differ from each
other, the description in the body of the manual takes precedence.
1. Handling of Unused Pins
Handle unused pins in accord with the directions given under Handling of Unused Pins in
the manual.
⎯
The input pins of CMOS products are generally in the high-impedance state. In
operation with an unused pin in the open-circuit state, extra electromagnetic noise is
induced in the vicinity of LSI, an associated shoot-through current flows internally, and
malfunctions may occur due to the false recognition of the pin state as an input signal.
Unused pins should be handled as described under Handling of Unused Pins in the
manual.
2. Processing at Power-on
The state of the product is undefined at the moment when power is supplied.
⎯
The states of internal circuits in the LSI are indeterminate and the states of register
settings and pins are undefined at the moment when power is supplied.
In a finished product where the reset signal is applied to the external reset pin, the
states of pins are not guaranteed from the moment when power is supplied until the
reset process is completed.
In a similar way, the states of pins in a product that is reset by an on-chip power-on
reset function are not guaranteed from the moment when power is supplied until the
power reaches the level at which resetting has been specified.
3. Prohibition of Access to Reserved Addresses
Access to reserved addresses is prohibited.
⎯
The reserved addresses are provided for the possible future expansion of functions. Do
not access these addresses; the correct operation of LSI is not guaranteed if they are
accessed.
4. Clock Signals
After applying a reset, only release the reset line after the operating clock signal has
become stable. When switching the clock signal during program execution, wait until the
target clock signal has stabilized.
⎯
When the clock signal is generated with an external resonator (or from an external
oscillator) during a reset, ensure that the reset line is only released after full stabilization
of the clock signal. Moreover, when switching to a clock signal produced with an
external resonator (or by an external oscillator) while program execution is in progress,
wait until the target clock signal is stable.
5. Differences between Products
Before changing from one product to another, i.e. to one with a different type number,
confirm that the change will not lead to problems.
⎯
The characteristics of MPU/MCU in the same group but having different type numbers
may differ because of the differences in internal memory capacity and layout pattern.
When changing to products of different type numbers, implement a system-evaluation
test for each of the products.

Preface
This LSI is a single-chip microcomputer made up of the H8S/2000 CPU with an internal 32-bit
architecture as its core, and the peripheral functions required to configure a system.
This LSI is equipped with ROM, RAM, a bus controller, data transfer controller (DTC), a 16-bit
timer pulse unit (TPU), a watchdog timer (WDT), a serial communication interface (SCI), a D/A
converter, an A/D converter, and I/O ports as on-chip supporting modules. This LSI is suitable for
use as an embedded processor for high-level control systems. Its on-chip ROM are flash memory
(F-ZTAT™*) and mask ROM that 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.
Note: * F-ZTAT is a trademark of Renesas Technology Corp.
Target Users: This manual was written for users who will be using the H8S/2319 Group in the
design of application systems. Members of this audience 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 H8S/2319 Group to the above audience. Refer to the
H8S/2600 Series, H8S/2000 Series Software 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 H8S/2600 Series, H8S/2000 Series Software Manual.
