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 Seres engineering team conducted strict reviews on multiple dimensions such as the functional characteristics, processing speed, power consumption performance, environmental adaptability, and cost-effectiveness of Hangshun HK32A040C8T3 MCU.Hangshun's MCU has successfully conquered the engineering team with its excellent performance, especially inhigh reliability and strong anti-interference capability.Additionally, HK32A040C8T3 features 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 uses 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 register, interrupt vectors can be remapped within the main Flash area. It also supports traditional Flash Level 0/1/2 read/write protection and Flash code encryption (self-developed patent by Hangshun).
