The GD32A490 series of automotive-grade MCUs continue to leverage the advantages of the local supply chain and adopt mature and complete automotive-grade processes. Product development and production management have passed the automotive industry quality system IATF 16949:2016 certification, and comply with AEC-Q100 automotive grade reliability and safety. safety standards, and has excellent electrostatic protection and anti-interference capabilities. It can operate reliably under high-risk conditions such as extreme temperatures, electromagnetic interference and vibration to cope with harsh conditions and complex tasks in the vehicle driving environment.

The GD32A490 series automotive-grade MCU uses the Arm® Cortex®-M4 core, runs at a frequency of up to 240MHz, and is equipped with up to 3072KB on-chip Flash and 768KB SRAM. Supports zero wait for code execution, with performance up to 355 DMIPS. It also integrates rich peripheral resources, providing up to 4 USARTs and 4 UARTs, 3 I2Cs, 6 SPIs, and 2 I2Ss. The USART supports communication with LIN.

In order to meet the application requirements of vehicle gateways, it also supports 2 CAN2.0B, 100M Ethernet and USB2.0 FS/HS communications. The chip integrates a TFT LCD controller and various multimedia interfaces, which is suitable for diverse scenarios such as vehicle central control, entertainment audio and video, and instrument panels. GD32A490 is equipped with 3 12-bit high-speed ADCs with sampling rates up to 2.6M SPS and 2 12-bit DACs to support automotive motor control. Up to 140 GPIOs can realize multi-load control of the BCM module.
