GD32A513KCU3 Automotive-Grade Microcontroller Product Introduction The GD32A513KCU3 is a high-capacity automotive-grade MCU from GigaDevice's GD32A513 series, compliant with the AEC-Q100 Grade 1 automotive certification standard. It is designed for 12V vehicle power supply and high-temperature industrial environments. Core Performance: Arm Cortex-M33 32-bit core with a maximum operating frequency of 100MHz, featuring built-in DSP instruction sets and TrustZone hardware security isolation. Supports hardware encryption and secure boot to enhance the information security level of automotive systems. High-Capacity Memory: 256KB main program Flash, 32KB operational SRAM, and 64KB data Flash (replaceable for EEPROM). All memory areas incorporate hardware ECC error correction to prevent data errors under extreme temperatures, making it ideal for storing large calibration parameters and fault logs. Electrical & Temperature Characteristics: Ultra-wide operating voltage range of 2.7V–5.5V, resistant to vehicle voltage fluctuations. Operating temperature range of -40℃ to +125℃, ensuring 15-year longevity in automotive applications. Equipped with BOR/PDR power-down monitoring, clock failure detection, and dual independent watchdogs to significantly reduce the risk of system crashes. Rich Peripheral Interfaces - Bus: 1× CAN FD (compatible with CAN2.0B), 4× USART/UART, SPI, I2C, supporting LIN node expansion. - Analog: 12-bit 1MSPS high-speed ADC, DAC, and multiple high-speed voltage comparators. - Control: Multiple 16-bit PWM advanced timers, 64-bit basic timers, hardware CRC, and RTC real-time clock. - IO: QFN32 package with 27 general-purpose GPIOs, large bottom thermal pad for excellent SMD heat dissipation. Package & Supply: QFN32 5×5mm compact SMD package, supplied in standard tape-and-reel packaging, genuine and new stock. The GD32A513KBU3 variant in the same package offers 128KB Flash, while this high-capacity model suits complex automotive control solutions with multi-algorithm and multi-peripheral requirements. Typical Applications: Body control module (BCM), automotive lighting/window/seat motor drivers, CAN FD sensor nodes, low-voltage BMS slave controllers, automotive wireless charging master controllers, wide-temperature industrial machinery controllers, and outdoor industrial data acquisition device
