The APM32F103RCT7 automotive-grade MCUs based on Arm® Cortex®-M3 core with integrated 256KB Flash, 64KB SRAM, and abundant storage to meet the demand for large-capacity cache for automotive applications. It provides a "dual CAN" communication interface and complies with 2.0A and 2.0 specifications, with communication rates up to 1Mbit/s. It supports independent USB and CAN, which is suitable for a wide range of car terminals and helps customers to expand more automotive scenarios. Certified AEC-Q100, it has been successfully applied in automotive fields such as car audio and video system, navigation system, central control system, BMS battery management systems, intelligent cockpits, ADAS, and EDR.
