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.

H8S, H8SX specifications

Renesas H8S and H8SX microcontrollers are part of Renesas Electronics' H-series of 16-bit microcontrollers, widely known for their rich functionality, exceptional performance, and versatility in embedded applications. These microcontrollers are ideal for a variety of applications ranging from automotive systems to industrial automation and consumer electronics.

The key feature of the H8S series is its high-performance CPU architecture, which includes efficient instruction execution, allowing for faster processing of tasks. The H8S series operates at clock speeds typically up to 24 MHz, providing ample processing power for complex applications. The H8SX series builds upon the H8S foundation with enhanced performance capabilities, including advanced instruction sets and support for higher clock frequencies, which can reach up to 40 MHz.

One of the standout characteristics of the H8S and H8SX microcontrollers is their rich peripheral set. They offer multiple I/O ports, timers, ADCs (Analog-to-Digital Converters), and communication interfaces such as SPI, I2C, and UART. The built-in ADCs allow for accurate analog signal processing, making these microcontrollers suitable for measuring temperature, pressure, and other sensor inputs in real time.

Moreover, the H8SX series provides additional features like improved flash memory capacity, enabling more complex applications to be developed and more extensive firmware to be stored. With the integration of a high-performance interrupt controller, the H8SX models can manage multiple interrupt sources efficiently, allowing for real-time response to events.

The H8S and H8SX microcontrollers also support a variety of development environments and programming languages, making them accessible for developers with varying skill levels. They are compatible with both C and assembly language programming, along with a range of development tools and IDEs (Integrated Development Environments).

In terms of power consumption, these microcontrollers are designed to be energy-efficient, making them ideal for battery-operated devices. With features such as low-power modes that allow the device to enter sleep modes when inactive, the H8S and H8SX microcontrollers help extend the battery life of applications.

In summary, Renesas H8S and H8SX microcontrollers stand out due to their performance, extensive peripheral functionality, versatility, and energy efficiency. Their rich feature set and compatibility with a variety of development tools make them a desirable choice for developers looking to create innovative embedded solutions across multiple industries.
