Fire hydrants are important fire control equipment, but in practical applications, there are problems with scattered installation and complex management of fire hydrants. As a result, insufficient water supply pressure and emergency repair and water outage at fire sites are common, seriously affecting firefighting work, causing significant personal and property losses, and affecting urban fire safety.

Therefore, intelligent fire hydrants are gradually emerging. What is an intelligent fire hydrant? It adds ultrasonic flow meters, sensors, etc. on the basis of traditional fire hydrants, processes the relevant data collected by sensors through MCU, and transmits the data to the cloud to achieve remote monitoring and management of fire hydrants, greatly reducing inspection and management costs.

The HK32L08x family of Hang Shun chip MCU products has the advantages of ultra-low power consumption, rich interfaces and peripherals, and safety and reliability. It is applied in fire hydrant products with limited power supply to reduce product power consumption and ensure long-term operation without the need for external power supply.

（3） High security design technology

The AES circuit implemented with embedded hardware can support key lengths of 128 bits, 192 bits, and 256 bits.
The embedded hardware read-write protection circuit protects the data security of the internal Flash of the chip.
The embedded hardware encryption circuit encrypts the programs and data stored in the internal Flash, preventing the chip from being opened and stealing Flash programs and data.

The management and maintenance difficulties of traditional fire hydrants, which are large in quantity and scattered in installation, have been troubling urban water supply and fire stations both domestically and internationally. With the development of 5G and Internet of Things technology, the roadside fire hydrants are endowed with a "smart brain" to achieve real-time monitoring and inspection of fire hydrants. This is a great blessing for safeguarding urban infrastructure and ensuring firefighting and disaster relief work.

The HK32L08x family of Hang Shun chips has been widely used in multiple intelligent fire hydrant products. Hang Shun chips are stationed in every corner of the city, ensuring that these fire hydrants are on duty for ten years with ultra-low power consumption and high reliability!

A solution for automotive gear shift switch based on Hangshun chip automotive grade MCU HK32A040C8T3

Throughout the global development of passenger cars, automatic transmission has been widely adopted. Its simple and easy to learn, convenient and intelligent characteristics bring drivers a more comfortable driving experience, and also better adapt to urban traffic. The implementation of the automatic shift function actually uses a gear shift switch instead of manual operation. The gear shift switch will control the shift fork and gear shift based on different engine speeds, vehicle speeds, and the driver's intention to press the accelerator. To achieve these automated operations, a shift switch requires a brain. The Hangshun chip M0 series automotive grade MCU HK32A040C8T3 is such a "brain", applied in gear shift switch schemes. Its main function is to receive signals from the gear shift switch and convert these signals into electrical signals that can control the car's engine, transmission, and other parts, thereby simplifying driving operations and providing great convenience for the driver. In the process of developing its new generation of electric vehicles, in order to ensure that the vehicle's performance, reliability, and safety reach the optimal level, after in-depth technical evaluation and multiple rounds of screening, Selis New Energy Vehicles finally chose a gear shift switch scheme based on the Hangshun chip HK32A040C8T3. The Selis engineering team has conducted a rigorous review of the functional characteristics, processing speed, power consumption performance, environmental adaptability, and cost-effectiveness of the Hangshun HK32A040C8T3 MCU in multiple dimensions. Hangshun's MCU has successfully conquered the engineering team with its outstanding performance, especially in high reliability and strong anti-interference ability. In addition, HK32A040C8T3 has high integration and flexible peripheral interfaces, providing engineers with greater design freedom and optimization space, making the entire electronic control system more compact and efficient. HK32A040 using ARM ® Cortex ®- M0 core, with a maximum operating frequency of 96MHz, built-in up to 124 Kbyte Flash and 10 Kbyte SRAM. By configuring the Flash controller registers, the remapping of interrupt vectors within the main Flash area can be achieved. And it supports traditional Flash Level 0/1/2 read-write protection and Flash code encryption (patented by Hangshun). Strong scalability 32-bit ARM CPU architecture, good ecological environment Rich peripheral resources to meet platform expansion Multiple packaging options available for LQFP64, LQFP48, QFN32, and QFN28 high reliability Car specification quality, compliant with AEC-Q100 Grade 1 Complies with ISO 9001 and IATFT 16949 quality management systems Supports -40 ℃~125 ℃ High cost performance ratio Equal performance/resources, with higher cost-effectiveness Quality service Complete ecological supporting facilities 15 years of design life, with a supply chain guarantee of over 15 years The gear shift switch scheme based on the Hangshun Vehicle Class MCU HK32A040C8T3 has been successfully applied in the Sailis new energy vehicle, which not only improves the electronic control efficiency of the entire vehicle, but also achieves lower energy consumption and better user experience. The Hangshun chip series vehicle grade MCU HK32A040 can be widely used in vehicle domain controllers, such as doors and windows, tail lights, wipers, anti-theft alarms, car keys, air conditioning, electric seats, etc. Hangshun Chip adheres to the strategy of SoC+32-bit high-end MCU in automotive standards.
