AT32A403A is suitable for the existing development ecosystem of AT32 MCU, such as hardware resources such as AT Link Family programming and debugging tools, as well as software resources such as BSP standard library and ICP/ISP programming tools. It supports IDE platforms such as Keil, IAR, eclipse, RT Thread Studio, and OS/GUI platforms such as RT Thread OS, FreeRTOS, and LittlevGL to improve the efficiency of automotive electronic product development.
The automotive industry is accelerating towards intelligent networked electrification, and information security is becoming increasingly important. AT32A403A has multiple chip security protection measures, including absolute read protection (RDP), random number Flash burning, and the sLibrary (security library) function developed by Yateli. It can specify a range to protect specific program areas with passwords. For example, after the upstream solution provider protects the kernel algorithm, it can be provided to downstream customers for secondary program development. When external expansion SPI NOR Flash is burned through MCU and expanded, the program and data in this section will be scrambled and encrypted by the internal hardware of the chip, providing comprehensive protection for MCU code.
Widely applied, enriching the automotive electronic intelligence experience
AT32A403A has the advantages of high reliability, high performance, and security code protection, which can be applied in car lights, windows, seats, BMS, fans, air conditioning, BLDC motors, sensors, T-Box, door handles, OBC, instruments, car central entertainment systems, EPS, reverse radar, ADAS, 360 look around, OBD, intelligent rearview mirrors, PM2.5, head up display HUD, wireless charging, alarm, PTC car heaters, etc., covering body control Multimedia information systems, instrument control, power motors, and emerging intelligent and real-time safety systems bring a richer intelligent experience to the automotive electronics field.
In response to diverse packaging and storage needs, AT32A403A offers a series of chips for selection, with 12 product models, including four packaging types including QFN48, LQFP48, LQFP64, and LQFP100. At present, samples of this series of products have been sent and officially put into mass production and supply in August of this year.
About AEC-Q100
EC-Q100 certification is a reliability testing standard for automotive electronic components developed by the Automotive Electronics Council, which has high authority in the global automotive industry. AEC-Q100 has a high certification threshold, a wide coverage of testing projects, and extremely strict requirements for the design quality, safety, and reliability of chip products. It is an important passport for integrated circuit manufacturers to enter the automotive field. AT32A403A has passed the AEC-Q100 certification, marking that the performance and reliability indicators of the Yateli car grade MCU comply with international car specification chip standards, and the product quality has been recognized and affirmed by the international authoritative certification system.
