Product Description：

The GD32A503VDT3 is a member of GigaDevice's inaugural GD32A503 series of automotive-grade microcontrollers, marking the company's official entry into the automotive MCU market in September 2022 . This series is designed following strict automotive-grade concepts and production standards to meet the high reliability and stability requirements of vehicle applications. It offers balanced performance, rich peripherals, and enhanced safety, serving as a mainstream choice for various automotive electrification scenarios.

Key Features：

Core & Performance：100 MHz Arm® Cortex®-M33 core. (Note: Some sources claim 120MHz, but this conflicts with official press releases.)

Memory：384 KB embedded Flash, 48 KB SRAM, plus dedicated code space configurable as 64 KB Data Flash / 4 KB EEPROM.

Automotive Reliability：Manufactured using a 40nm automotive-grade process. Operating temperature range: -40°C to +125°C. Minimum operational lifespan of 15 years and compliance with AEC-Q100 Grade 1.

Power Supply：Wide voltage supply range: 2.7V to 5.5V.

Communication Interfaces：2× CAN FD, 3× LIN, multiple USARTs, I2Cs, SPIs, and an I2S interface. A flexible MFCOM component for additional interface configuration.

Analog & Control:12-bit ADC (1 MSPS), comparators, DAC, and multiple PWM advanced timers for motor control.

Safety Features:ECC for Flash/RAM, CRC for data communication, built-in voltage/clock monitors, and high ESD/EFT immunity.

Primary Applications:

The GD32A503 series is designed for a broad range of automotive electronic control units (ECUs):

Body Control & Motor Systems: e.g., power windows, wipers, HVAC, smart door locks, power seats, electric tailgates.

Automotive Lighting Systems: e.g., ambient lighting, dynamic taillights.
